Can we all agree that women are not a “niche”?

I see this word thrown around constantly in books and videos. <br><br>Or we’re referring to men as a “niche” too? I’ve never seen that. <br><br>Trying to make up some fluffy term about how everything is about men and that justifies putting women in a box?<br><br>I just don’t understand why this term is so widely used, it’s so weird to me.
