So before I start, I want to make sure people understand there is no morality involved in this. These are natural.

Bluepill pushes the female imperative: which is essentially everything to enable their mating strategy. AF/BB is part of this strategy, aka seeking the highest value male possible. Then settling for a more beta male if that alpha does not stick around.

Men are biologically disgusted by this because it is similar to cuckoldry, just not as up-front and direct.

Redpill pushes the male imperative; which is to 'spread your seed'. Everything is done in a matter to achieve the maximum amount of sex with the maximum number of women (why they oppose monogamy/marriage).

Women are biologically disgusted by this because they can't understand why a man would need to fuck everything that moves. It makes them feel cheapened. Being able to compartmentalize sex bothers women at a core level.

The key for people is understanding that these imperatives are innate and not intended to be malicious.
