I have gone back and forth on this issue, first taking the obvious stance of good for them, then thinking perhaps they should have left it. I think that without really having the chance to see what the content of the app was, it is hard to say what action is correct. Of course the point should be made (and has been) that apps in the Apple app store are inherently endorsed by Apple, both by being there but more so because Apple has some sort of approval system in place, meaning that they are supposed to be aware of the content. The point has already been made that this is like a bookstore refusing to sell a book, or a website deciding to do so. It is their decision to do so much the same way that if I were to write a book claiming the Christianity was wholly wrong and leading people to their doom, a Christian book store would most likely not sell my book.
This however overlooks one thing, the content. If the content were some sort of explanation of why gays are wrong, or 'immoral', then it is somewhat covered by the First Amendment. If however it is trying to claim somehow that it can 'cure' gays, it would not be (I think. I am by no means a expert on the Constitution, nor a lawyer on the subject). The difference would come from intent from my understanding. In the first, you are expressing your views and opinions, the second, an effect. If you could prove (Scientifically) your results, it would be one thing. But more then likely (Again, has I have not seen the content), we are talking about your religious views, which is bordering on dangerous territory. Apple, regardless of how you feel on this subject, has a right to protect its image, even if it is not the same has yours.
That said, I was brought out and decided to comment on several of the post here. Several of them have gone so far as to claim that Homosexuals do not want to get married, only to retract the statement and claim married in their 'definition', has well as pulling biblical quotes. First, the Bible is full of 'laws' that are meant to be followed. However, by your own arguments, these laws are not meant to be followed. Christians themselves say, when confronted by these laws, that they were meant for a different time, and are not applicable to today's world. If this is so, how is it that those laws are not meant for today, but the only one in the Bible pertaining to Homosexuality somehow does? Where, and what, exactly is the process by which this decision has been made? Those attempting to use the Bible have always chosen to pick and choose what 'laws' are meant to be followed, not to mention the process of interpretation that inevitably takes place. While I don't believe that it is an all or nothing thing, the simple fact that this inconsistency is never mentioned unless brought up by outside sources is hard to overlook. What few explanations that I have heard (and one was here), fail to address why one law is outdated but another is not.
Second, while marriage is linked to religion, the -rights- attached to them are not. The argument was made that Homosexuals do not wish to marry. When this was pointed out to be false, the statement was changed to marry in the man and women sense. While this may hold truth where religion is concerned, a major problem arises from the fact that it is untrue where rights are concerned. A Civil Union does not even grant the same rights. I have taken this argument stance before, and will again. Has a Bisexual individual, I should be able to marry whom I wish, male or female. If you feel that this intrudes upon your 'religious rights', I would be happy to grant Civil Unions the same rights. This way a government can grant the Civil Union while leaving your Religious Marriage alone. This however overlooks a bigger problem, what this has to do with Homosexuality.
After leaving this forum?, and cursing some other subjects to calm down, I have returned to state simply that this app crosses into dangerous territory, both with its name and supposed content. I feel that it should have been taken down (If even allowed through at all). While reading this I was reminded of a different forum in which the discussion was about whether or not gays should be given the rights of marriage. In it an individual alleged that Homosexual individuals were horrible due to the fact that he was raped by one, assuming my memory is correct. Others in the forum, after prying said fact from him, pointed out that the actions of that one individual certainly should not doom all others. I have come back to this subject time and time again, wondering what would happen should an individual claim they were raped by a Heterosexual individual? If one were to make the claim that all Heterosexual individuals were horrible and should be denied rights, would that individual still stand behind them has well due to the trauma they endured? I think not, most would stand against such actions, and work, much has the posters did there, to help him rethink such sentiments. More-so it brings to point the fact that simply because you believe it, or I do, does not make it law, nor right.
While I believe that the app should have been taken down, I have come to said conclusion not because I am Bisexual, not that I am not religious in the sense of following a set religion, but more so from hearing both sides of the argument (In so far as this forum has provided). I stand ready to support any apps that religious individuals wish to put out that would be for their religion. The few 'Homosexual' apps i have seen are more about support, or hooking up. While I can not speak for all the apps, it seems that if a 'Religious' app were released for this purpose, there would be support for it. Claiming that this is an attack upon your religion is a log in ones eye.
I apologize for the long post, it is six in the morning, and I may be rambling a bit now.
