Riley Gaines came equal fifth with a trans woman, and then spun that into a narrative where competing with trans women is unfair on cis women. The top four finishers were cis women. She lies, constantly, about how the system was stacked against her, when she's just not a very good swimmer. She brought the conversation onto this topic, that she would actually be able to excel if the playing field were "fair". Pointing out that she wouldn't is not only reasonable, but it's important to do, because it lays bare the fact that both her and the trans woman that's caused her to feel so disaffected are equally not that good compared to their peers.

It's really bold of you, a cis person, to come into a trans space, and tell us all off for 'being mean to' someone who you admitted you had never heard of, when she is a TERF who has used her platform to help pass trans sports bans in a number of states. It has a real "you must be tolerant of the intolerant" vibe to it. I think you should try and be introspective about the privilege that you have, that's led you to have this opinion.
