Honest question, you say you compete for fun, but what about the folks you beat who are competing for the sake of competition, which is a little different than fun? I am generally open minded at least in comparison to folks I encounter but I can’t square this one in my head. I am just one person with a single opinion but would like to better understand where I am wrong on this topic.
I'm not an athlete, but here's my understanding.
Being on feminine hormones pretty much removes any advantage if you've been on them for a while. There are typically rules about that for (at least) high level competitions. You can't just walk in and state your gender for that kind of thing.
Honest question, you say you're generally open minded in comparison with people you encounter but have you considered you're generally not?

We are not talking about elite athletics here. If someone is upset about a transwoman finishing 150th in the local 10k race they need to work that out with a therapist or something.
