Let's define what a slut is. A slut rides the cc. A slut believes there's nothing inherently wrong with a high partner count. A slut doesn't care if she spends her youth chasing alpha cock, then settles down post wall for a beta provider. She is unashamed of her actions even in the face of criticism. She doesn't care because she views men as disposable.

A red pill man is a man who has given up looking for unicorns and joins the cc. After a literal decade of faithful trust in the system, he becomes aware of how rigged the game is. A red pill man doesn't care that he is part of the cc because his youth was void of positive female interactions and sees the potential for a Neverending cascade of young pussy by applying the very concepts that he has observed women actually being attracted to. Marriage is the last thing on his mind now. A red pill man is unashamed of his actions because he spent the majority of his life walking on egg shells trying to appease women with no success. He doesn't care because he knows he is disposable.

Any criticism of red pillers being male sluts is laughable. There's no reason to care.
