I am male :)
I am an LTA tennis coach
I am an ABTO referee (that is the bod who wanders out onto court at Wimbledon to make decisions on the rules - then wanders back to the bar for a G&T - not the umpire bod who sits in the chair!)
I am very anti the ability for e.g. a boy / man to self-id as a girl / woman and play against them - it is phenomenally difficult to keep girls - esp. teenage girls - in the sport, this will basically kill girls tennis...
I have filled in the questionnaire as someone actively involved ( RatRolyPoly ) explaining exactly why it would be a stupid idea...
it is possible to have mixed sessions for children up to c. 12 years old - (often the earlier development of girls balances the strength of boys) but beyond that age it is inappropriate. There is mixed tennis (our club plays league mixed tennis every winter), but even then it would not be appropriate to have someone of one sex ID as the other sex and be allowed to play as that - the mixed sex works because it is balanced...
Everything in this current push seems to be about giving men the opportunity to walk in and take over women's spaces - and no advantage were women (transmen) wishing to do the same the other way...
I am not 'pro woman' or 'pro man' I am pro humans - and respect that it means that we are born differently, have different needs / different physiologies / etc. and therefore it is reasonable to give space for people to do things as mixed-sex, or as either sex on its own (and a trans woman is not and never will be a woman)
I am not on twitter - but has anyone tweeted Judy Murray to join in the discussion as a highly respected woman in tennis / Jamie & Andy as men in tennis...?
