Why is it OK, for males to compete against females?

Where? What country and sport?
There is no single rule across all sports regarding transgender female participation. Each sport sets its own guidelines based on its unique physical demands.
That being said, trans women that are allowed to compete against women are usually eligible once they have undergone hormone treatment. Meaning trans athletes have undergone suppression of testosterone therefore gender-affirming healthcare. They have no biological advantage.

It isn't lost on me that men that complain about this are usually quiet about women suffering sexual, physical and emotional abuse as on a much larger scale.
Unless a woman herself complains about a proven disadvantage in these sports, I don't think we need men with tunnel vision to do it for us. I say proven because the last time this happened, a biologically born woman's life was almost ruined (imane khelif)

Idk about that stats. But I do agree there should be separate categories in competitions for those who chose to change their sex.

Physical strength wise, there'd always be the difference that comes with being created as a woman and as a man.

Some people would throw mud at that and come up with different justifications to suit them though.

Child poverty is rising again. Access to Healthcare is at risk. Housing affordability is out of this world.

But sports is what we consider important here.

Well I do know for a fact that if I were to win a competition by using steroids to build up muscle mass and enhance my performance that I would be disqualified for cheating.

That is bogus information.

It is NOT okay.

Let them play in the Tranny league, and leave women's sports alone.

its not.. hence the pushback

why do you care about this so much?
