I can personally attest that I never had a female friend, not even once in my entire, sad, wretched life — although it's not as if I am interested in 'friendship' with a woman anyway. As far as I can tell, the very notion of male-female friendship is preposterous and cucked in its very essence, save for extraordinary cases; the female is a vacuous, unintelligent, feebleminded creature — incapable of much rational reasoning, abstract thought, or really, anything that one could classify as surpassing the realm of 2-dimensional thought; hence, I cannot see a reasonable motive for why one would befriend said creature — purely for the sake of 'friendship.'
It is not as if engagement in meaningful conversations could possibly occur; there is also no mutual benefit, for the female is parasitic in her nature, and any benefit would inevitably end in the woman's end — an exploitative, one-sided relationship wherein the woman strings the man along, or utilizes his resources or knowledge; further to that, there is no shared experience one could bond over, or any similarity between the various happenings in each party's lives, especially when you are an incel. Most of these things also apply to friendship with the vast majority of men, albeit to a lesser extent, especially when the man is a fellow incel.
The point is, even if no sexual interest is presupposed, there is no logical reason for such friendship to exist.
Besides, in reality there is no male-female friendship without a level of romantic tension, typically from the side of the man, which will inevitably end up unreciprocated when the man is unattractive, and it will render exploitation of the man easier. This is the most cucked situation you can willingly put yourself into. While you are coping with a pathetic friendship with a foid that perceives you as nothing more than a measly bug under her boot, she is juggling multiple guys exactly like you, and having sex with chad. Any man that is fine with that is a man unworthy of respect; I couldn't imagine spending time with some vacuous whore, under the pretense of friendship, while knowing she sees me as subhuman and has sex with another man.
