Why is physical strength always brought up by " anti feminists?"

A random dude in reddit was debating with me a few days back They told me alot of bullshit like how " women hate vurnerable men " and other werid claims

But one that really stuck with me is that apparently women needs a man to protect her from rape cus of women's lower strength

Why is physical strength always brought up by people like them? Is it really a factor to consider? Or is it bullshit
