It seems as tho people these days advocate for people to do whatever they want in regards to sex and relationships rather thats whats the right and responsible decisions.

Two main examples I can think of that fit with this is polygamy and sex work.

Polygamy often more times then not doesn't lead to a healthy relationship and causes jealousy in other partners. I once had a debate with a polygamist that said "me and my partners get STD screening regularly" to which i said "the fact you have to do that to begin with is a red flag" plus if a polygamous relationship leads to them having kids this can have serious damage on the kids development into an adult as they often won't get to see their mother/father as often as they should.

Next is sex work this is neithier responsible nor does it tend to lead to a healthy mindset but it seems as tho whenever you point out any of the downsides to it or debate it people act like you disagreeing woth it is the worst thing to happen to humanity since the holocaust. Most of the time women don't choose sex work because its "empowering" or "fulfilling" they do it because its the only way their finacially stable or because they were tramutized as a kid and later became this way as an adult in order to fill a void or vent out. It also develops no future skills and your reducing yourself to nothing more then aasturbation tool and exploiting your body (does that really sound "empowering"?)
