Since when have gaping flaws in a concept been a deterrent against people trying to implement it?
Your typical Internet White Knight is most likely not explicitly aiming to get laid, but simply following the classical role model they've absorbed via Hollywood: women are weak and need to be defended, good men defend them (and get the girl in the end).
It can get a bit comical but the real problem is that it takes the form of personal defense in specific cases, and is focused on women. So males getting treated like shit are unlikely to get any help or even sympathy from a White Knight, and they're unlikely to spend any effort on actual solutions to a toxic atmosphere.
