Just like blacks or gays should derive joy from people stealing their dress and lingo? Why? We create communities to find like-minded people who enjoy the same hobbies. Claiming that they "should be" anything is unhinged and part of the reason they hate you so much.

You are just ignoring reality and pretending that because the label is the same that the implementation is too. No, they don't share hobbies, they share the barely share the label and have polluted the term to the point that it's unusable.

In the past gamers were exited for new engines, pushing forward graphics and gameplay into the unknown. Now we all just use the same engines and "gamers" are excited that their niche subculture unrelated to gaming is painted on the 15-year-old engine. There is nothing "gatekeeping" gamers other than your own interest in games, if you don't have any genuine interest in games then you aren't a gamer, it's really that simple. Compare the behavior of Eminem and Vanilla Ice from the start to the peak of their career (background, come-up, acknowledging the White elephant in the room, co-sign/credibility).

What did we get for gaming? A hostile corporate takeover and femwashing and then the total collapse to were people only play a handful of forever games and indie titles. People claim that identity matters, that's not true, participation matters. If you are gay/bi but don't interact with the gay/bi community out of some prejudice or you are closeted you shouldn't feel justified co-opting gay culture when it becomes profitable. Similarly if you game, but thought that was wack nerd shit and you would never tell anybody beforehand (men&women, but mostly men), but now that there is money it you want a slice then you are just an exploiter.

So "blacks" and "gays" (black people and gay people) can't be gamers?
