So what do they do once they are outside of the "safe" gym? If you need a separate workout space because women are around you in gym clothes then you're going to struggle a lot in the rest of your life. Do they need separate beaches, swimming pools, have to stay at home during the summer months?

I'd suggest counselling with a professional would be better use of their time.

Teaching my kids how to act normal by taking them to MAN GYM where half the people there are taking steroids to bulk up and the other half don't know how to talk about anything but GETTING PUMPED

To promote more serious discussion in shitpost: One of the problems of gender separated facilities is it makes everything more complicated for parents like that guy that got arrested for taking his daughters into a women's restroom.

There's a lot to be said about 'safe spaces' but imo those spaces should not include any infrastructure like gym equipment, pools, toilets, operating rooms etc. It makes a lot of sense to separate rooms where people might be disclosing addresses, storing clothing or chatting but its maybe less necessary to separate spaces where toilets and gym equipment exist.

This is why pools are generally co-ed but the changing rooms are usually gender segregated and its often less about protecting people and more about creating less spaces for like a couple to have consensual sex in public.
