Yes, deflect the question, misrepresent the issue, and blame everyone around. Just avoid any introspection.

There is no "worth it" here for the non-queer gamers in the first place. It costs them (seemingly) nothing to throw queers under the proverbial bus and oppose any inclusivity. The only thing stopping people is sympathy and goodwill. Being a decent human being. Which tends to go out of the window quickly, when you actively try to destroy what those people care about. People don't have sympathy for people that "picked a fight" with them first. They just "fight" back.

And before you pretend games are insignificant and people shouldn't do this "just because of games", remember you picked this "fight" because of representation in games as well. Can't have it both ways. Games either don't matter (in which case what are we arguing about) or they do.

Gamers care about games. They have always pushed back hard against people messing with their games, whether it is "concerned parents" (religious conservatives), queers, or payment processors. If you believe that it is just homophobia, you are deluding yourself.

So I ask you again, is it really worth it to push things like SBI, that produce objectively bad games for everyone, knowing it will destroy sympathy and goodwill you have with gamers?

You don't have to answer here, just think about it. Because you can't expect understanding and sympathy from others if you are not trying to understand and sympathise with them as well.
