It sure is. The numbers vary, because all they have are estimates, but the upper number was less than 100. Though according to GLAAD, that number may be far lower. The president of the NCAA told a senate panel that he knew of fewer than 10 trans athletes, out of 510,000. Even if that number was 100, it is still minuscule.
Kind of true. He’ll gladly make a pass or aim sexualized remarks at all sorts of women, whether they’re random underage girls in a dressing room or his own biological daughter. Equality!
At the club level it's not atypical to see mixed gender, but in the professional level it's split by gender. I think they can get away with it being mixed at lower level of competitiveness because gender doesn't matter as much as in other sports. However, from what I've seen, size/strenght/weight definitely do play a factor in the sport and it does favor men.
Edit: By club level I mean like university fencing clubs. At the club level competitions can be mixed gender or split gender. Anything above club level is split gender.
