It's not hard. Really, it isn't.
Just look at HEMA. Using my sport as an example, HEMA attracts a lot of white supremacist chuds. So what does my club do to alienate them? We state our values up front, and we live those values. Every single one of us.
When I joined the beginner's class, the coach walks in front of all the new students and says, "HEMA stands for Historical European Martial Arts. Some people mistake 'European' to mean 'better than everyone else'. If you believe that, there is the door. In this club we respect people's identities and pronouns, if you cannot do that, there is the door. "
Even if the chuds stick around after that, eventually they do leave. Why? Because we make all of our values explicitly known through our interactions with each other in the club, and we shut their bullshit down whenever they try something. The fact that so many of us are queer, or trans, or just real as fuck allies alone does it sometimes. That we don't tolerate any amount of fuckery and if somebody says a racist or homophobic or misogynistic "joke", they get shut down by the bearded white cis men who they incorrectly assume will have a laugh with them. And then those dumb racist sexist fucks leave. And never come back.
We don't have to kick them out. We will take their money as membership fees until they either change their mind and grow as a human being and become an actual respectable human being, or until they cower and leave. They always self-select for us.
And that's how you fucking do it.
