First off, they're called "Muslims". Crazy, I know. What you said here is technically true, but hold on...

Also true, but the thing is, most people have learned to stop being dicks and recognize that different people have different beliefs. Going around saying "You are stupid and wrong and I hate you", while covered by Free Speech, is completely retarded and pointlessly offensive. You simply don't do that.

and Aethists believe both is a lie, and a threat to the one true belief(That God does not exist.)
I wouldn't call any religion a "lie", per se. Also, Atheism isn't a belief, it's the lack thereof.

The T-shirt didn't say, "Muslims should be killed." It said, "Islam is of the Devil," Which is basically what every religion believes about every other religion-that every other religion is a lie which keeps people from the truth.
Actually, this is mostly only true of the Abrahamic Religions. All of them seem to have this rule saying "We are right and everyone else burns in hell". And as I said previously, most people accept the fact that others have different, occasionally conflicting beliefs, and just learn to deal with it instead of being an asshole. It makes little difference that it said "Islam is of the Devil" as opposed to "Muslims should be killed". Neither of them could possibly lead to a constructive discussion, and both are needlessly offensive.

Edit: And as I said earlier, if someone walked into school wearing a T-Shirt that said, "Christianity is a lie," nobody would care.
I'm not entirely sure about this. It may be easier to poke fun at Christianity in many places where it is represented by the majority of the public (there's this weird rule where you can't make fun of the minority, but the majority is fair game). However, regardless of the consequences, it would be completely pointless and do nothing other than say "I'm an asshole, look how offensive I can be".
