The problem with the interpersonal blackpill is that when people find out about it, they feel used, like a means to an end. I guess it's ethical to announce it to people before interacting with them, but that's so outside social norms, that I don't see it happening. Moreover, it necessitates the question, is it easier than being kind, caring and warm to people and form genuine and meaningful connections?
