Personally, for the same reason that I get annoyed when streets get renamed. This community isn't named the way it is to support hate and the vast majority of its users disagree with hateful viewpoints, it's named like this so people can find the community of PC enthusiasts that they're looking for. This is what it was on reddit, thus it's the same here.
To be blunt, if people don't like the name, the best solution is to stop posting content here and instead post in an alternative community with a name they find more suitable. Nobody's here for the name, they're here for the content and the people and they'll migrate if those do. Just like reddit's recent exodus.
So that episode of South Park where they make fun of rednecks by having one say "If you don't like America, then you can get out." is literally exactly what you are saying here.
There’s a quite a difference in saying that about someone’s home country, which is a pain in the ass to leave, vs about a community people can opt into and which does not really shape their lives
