They do. It’s a BS pose where nerds claim to be “nice guys” (unlike those brutes and jocks over there), behave just like you see here (because they don’t like or are scared of women), and then whinge that they’ve been rejected because they’re nice guys. Amanda Marcotte was talking about them more than a decade ago.
The NiceGuys™ pull directly from the incel handbook these days – it’s all they know. “Wahhh, I’m a supreme gentleman. Look how I ordered for milady at the restaurant! Why won’t women sleep with me? I’ll show them!”
