I think one of the tactics of TRAs is to minimise the impact of men performing in women's sports by saying there are bigger things to worry about before posting a random series of other issues within sports generally.
This is true of TRA arguments about anything - why do you care about trans women in women's prisons when women in prison have other, worse problems such as being assaulted by male prison officers? Why do you care about women being assaulted by trans women in changing rooms when most cases of assault happen in the home? And so on and so on - the endless deflection.
Other top tactics:
Why are you so obsessed with trans people's genitalia? It's creepy.
You mustn't criticise trans ideology because that will lead to violence against trans people.
If you refuse to validate trans people's identity, they will kill themselves.
On and on it goes, a never-ending stream of irrationality, emotional blackmail, straw man-ism, ad hominem, all in response to sensible people pointing out that humans can't change sex.
