Broadly speaking, you probably agree with the large majority of the views commonly attributed to whichever group you identify with - what are the exceptions? Something that if you mention without a caveat immediately makes people jump to conclusions or even attack you?
There’s enough biological diversity that fairness is basically an illusion anyway. I don’t care enough about sports to have a strong opinion. I think it’s fine to say giving up competitive sports is a cost of gender transition. I might think it’s also fine to let trans athletes compete except I would hate it if the women’s league became the trans league or if poor young kids felt pressure to transition in order to compete at a higher level and get life-changing scholarships or even a professional career.
Is that a legitimate fear? Maybe not. At the end of the day, I rarely watch sports. I would support letting them compete and seeing if it is a problem before passing laws to fix issues that don’t actually exist.
