This is the exact "sentiment" at my liberal college. This is what is taught and what is entirely accepted by my peers.
In classroom discussions I have seen 95% of the room support legalizing drug dealing and prostitution. When I try to appeal to their sense of right and wrong or some kind of morality or any kind of admiration for what is sacred, they just give me some kind of immature liberal interpretation of things "if they aren't hurting anyone" "doesn't affect my life" "do you want the government to control everything"
I confronted the "professor" very perturbed with her because she just got done showing us a video of how we should legalize prostitution because the girls are being beaten and they can't go to the cops and the fines are expensive. The teacher made no attempt to show or discuss a dissenting opinion. I said to her "you just want to be able to do whatever you want, anything goes?" then I tried to explain to her the simple concept that in a society we can't just let everybody do everything because they affect and influence those around them.
Her response was to smile at my condescendingly. She felt above defending herself and probably knew she was heavily under qualified to discuss morality or right and wrong because she doesn't have these faculties. Or maybe in her mind this was being "objective", showing us her opinion in a YouTube video then steering the classroom discussion to support it without expressing it herself or showing us alternative opinions. Some drones in the class starting jumping in to defend her telling me this would raise tax revenue and it wasn't the cause of war. Simple minded people whose only concern for their neighbors and environment is how it will affect their wallet.
This is the scum ruining the society. Not the sinners who destroy themselves, but these immoral broken individuals who only care for themselves and their own lives. There are so many like this now they unite these opinions together and form a mob that tells them this line of thinking is correct.
You really can't argue morality or what is sacred with people who have no idea or feeling of what these are. Sometimes I'm shocked when I learn the actual beliefs and opinions of some people, and how they are able to interact with and be respected by others with this deep evil inside of them.
Sorry for the tangent and going off topic but I was in a classroom of predominately girls where the entire room said we should legalize prostitution and I'm still sickened and angry about it. One girl's quote was in a soft feminine voice "What's the difference between a guy and girl meeting at a bar and having sex and a prostitute receiving money for sex?". I was disgusted with her immediately and appalled at how she viewed human interactions. This is the best and brightest next generation. If you don't think they are bad enough to bring on the Apocalypse imagine their children or when they are in charge of government.
