Blackpilling most normies means nothing
The only places this would usually be worthwhile is if you're in some subcultures, groups or activities dominated by mostly introverted or outcast males. They can probably directly relate to blackpill issues, and to being judged based on shallow reasons, so it could spread and be meaningful among people there. Some possible places it would be easier are some metal scenes (ik metalheads are often cucked now, but some local scenes might still be more receptive), niche genres or activities, gamer groups, etc. A few jobs might qualify, but in some fields it's rare
Around normies, it's generally not worth going into explanations of the blackpill or whatever. Just making jokes or memes about it is usually better. Many misogynist ideas spreading among younger normies are sort of vague redpill/blackpill memes and laughing at jokes about foids, so that might be a more effective vector. In the 2000s, music about the problems with girls was fairly popular, and feminism has killed most of that, so there's still a niche to fill there. But they typically won't have a significant reaction to it, and might just ignore it in practice due to their normie cognitive dissonance
