men are slowly weeding them out by giving them the silent treatment, which is funny given how that's normally a woman thing to do.

"Silent treatment" for women is a tactic of emotional manipulation employed against people that care about them (family members, friends, husbands) - it is used by the woman to show "how little she cares" about the target to hurt that person. What you're describing men doing is different - it's not to emotionally manipulate women, but rather just a matter of ignoring random people who aren't worthwhile interacting with. Don't conflate the two, they aren't the same thing.
