@Cousin_Isobel @Flick I think some will do shorthand in their arguments, mainly concentrate on one single aspect, but the fact remains, there are multiple reasons why this is plain wrong.
Historically speaking, when it took so long for women’s sports to be taken seriously and some men come along and claim their place in those sports.
Some lame male athletes figure they have a better chance at recognition if they self-ID into women’s sports.
The biological aspect of male strength, stamina due to a bigger lung and heart capacity.
The fairness ideal in sports.
The dangers of serious injuries to female athletes caused by men.
The loss of scholarships to girls and women who cannot afford higher education.
Etc.
I think all the reasons should be declined in the argument for being against male presence in women’s sports but people now, due to all sorts of reasons, have short attention spans, so we trim the reasons to the simplest possible number. No use throwing a wall of info to some people, they zone out.
