In my personal experience as a very promiscuous person, my partners mostly are like "meh" and are occasionally like "oooh, hot." According to TRP theory, they would be faking this preference in order to pump and dump me, but the ring on my finger says otherwise.

However, I observe that I am poly, sex-positive, and fairly open about my promiscuity, so there's a significant selection effect here. The guys who don't like sluts aren't in my dating pool to begin with, and the ones that somehow manage to make it in there avoid me.

I think a similar filter effect may be happening for TRP. They draw from communities that happen to be full of men who are really repelled by sluts, and the few pro-slut men who happen to join the community are quickly repelled by all the circlejerking about how disgusting sluts are. It's as if you went to a feminism subreddit and asked for advice about how to date women and concluded that women were universally attracted to men who read bell hooks.

I mean, TRP has its explanations about why you shouldn't marry a slut (STIs, alpha widowhood, pseudoscience about oxytocin) and men who like sluts have their explanations about why you shouldn't marry a non-slut (lack of sexual enthusiasm, skill, and openness). TRP has its bullshit evopsych (cuckolding) and men who like sluts have their bullshit evopsych (partible paternity). To be honest, I feel like all of you are rationalizing preferences that you hold for whatever hindbrain reason people have any preference.
