Should transgenders be allowed to participate in competitive sports?

[Velasco]

The criticism of transexuals participating in female sporting events is valid, as there are obvious male biological features such as increased height and more muscle mass which give then an unfair advantage in female sporting events. You can't explain away biology.

Professional cis women can have thay advantage over other cis women.

But those are natural biological advantages that aren't helped along by taking testosterone or other drugs that boost muscle mass.

Hormone replacement therapy is about replacing testosterone by estrogen (or vice versa), as the name implies. Trans women take estrogen and testosterone inhibitors that reduce their levels of masculine hormone and the therapy has secondary effects such as muscle mass reduction. Why do you guys give opinions on issues that you ignore? It'd be more simple and easy if you tell the truth and say "I don't like these people"

Sports should not be divided by gender to begin with. I still don't know why women can't play in baseball, men and women together for soccer,  hockey, basketball, etc.

there are no gender rules in any of the pro US sports (as far as I know, if there are I would love to be educated on it), women CAN, theoretically, compete at the highest levels of sport.  They just never would (except maybe in some extreme situations, I'm thinking maybe a relief pitcher with a stupid good knuckleball, possibly a goalie in ice hockey), certainly not in any physical sport where the competitors are often in contact with each other and speed and strength are every bit as important (if not more so) as skill and knowledge of the game.

This might work at the little kid level, but nothing past puberty.  There is a reason the top women's teams practice against high school boys teams.

Really, then? The speed difference between men and women is more negligible than the speed difference between black people and Asian people. Maybe we should segregate soccer and races by race, since different ethnicities have an “unfair” advantage? Should Usain a lot from an elite, speedster soccer league “Blacks only,” since basically no Asians or Caucasians have ever broken the ten second barrier?

I don't think that's remotely true. Where black athletes overperform on the world stage, it tends to be because they come from high-altitude East Africa and so are essentially getting an oxygen boost when they compete in lowland areas. Can you show evidence to support this assertion statistically?
