I'm not into sports, but I've been so angry about this.
Trans women have loads of advantages, even if they have had gender reassignment. They are taller, faster, stronger, have a longer reach, etc. Not many women could win against them, and yes, female sport as we know it will cease to exist.
People are too scared to address this now, for fear of being labelled a bigot, but the day will come when the world has to have a re-think. DH reckons it will be a high profile female boxer being killed in the ring by a trans opponent.
What strikes me about all this as well, is what on earth is going on in the minds of trans athletes when they win? Do they really go home thinking they are the Champion? Is there no self reflection at all, or any feeling that maybe they cheated? No awareness, that if they had competed against men, they wouldn't even be in the top 1000 in their sport? Are these people that self indulgent?
I can't imagine running in a race against 5 year olds, winning and then really thinking that I had won fair and square.
