I was going to agree with you overall when reading, but when you mentioned that you are glad 18+ games are banned then I got a bit of a frown.
I am not saying I demand my bloody games so I can slaughter innocents, in fact some of my favourite games are things like Doom, shooting daemons from hell, and Black and White, looking after my little towns making sure they have their needs. But when you say you support the people who can press their opinions onto other people that kinda rattles my cage. Fair enough if you don't want to be further involved with a violent game, I can agree that imagining the people you harm are actual loved ones can be a bit disheartening. But when you force this onto other people who can distinguish a game from reality that is too far.
I can play games and be fine with killing innocents, I know they are scripted entities that will dissolve the second I leave the screen, or quit the game. These bits of data do not have full lives. I don't feel disgusted when I close a word document, it is the same process. You are ending a piece of data from currently running.
Games just give it a more literal visualization. The difference is I know intellectually and emotionally that this is bits of data stringed together. Similar to reading a book. When I read a fictional story and character has a troubling past, friends killed, village destroyed, contact with mafia or hitman etc etc. I can tell that it is suppose to tug at me emotionally but I can also tell it isn't real. Now if it was a news report it is slightly different. But as I have stated, I know intellectually the difference from fiction and reality.
But to my main point. Again, fair game if you don't want to expose yourself or your children or your friends to this kind of media. But if you ever dare try to impose your view onto other people you can bet I will be there to fight back. I can not stand in any shape, way or form censorship, especially against a type of media that is fictional. Snuff films I can understand. A game where pixels and sprites have the possibility to be harmed I can not.
Overall: No, I do not think the current state is morally wrong. People are genuinely smart enough to distinguish reality from fiction. But it is fine if people don't want to fully participate in those types of media. No one if forcing them to. But if you force other people to not be involved, that is just despicable and selfish. Censorship is ethically wrong.
