re: "but there should be at least some connections between people who engage in relationships"
You are free to have whatever kinds of relationships you want. Others are free to do the same. Who the f**k are you to tell others what kinds of relationships they should have? Mind your own f**king business.
re: "we have normalised hookup culture and sexualization"
This is absolute bulls**t. Young people are having less sex than at any time since the 1950s. Yapping nonsense about "hookup culture" is a stupid scare tactic. It has no basis in reality. All the data show that our society is more prudish, sex-phobic, and puritanical now than it's been for 4 generations.
"sexualization" is a fashionable buzz word these days, but anyone who takes some time to think it thru realizes that the whole thing is utter bulls**t. It makes no sense on any level. The word means 10 different things, but also means nothing.
Sex-phobic wieners all throughout history have been writing endless complaints of "OMG! Everybody's so promiscuous these days. It's horrible!". You can find examples of it from every decade going back thousands of years. It never changes. People always like sex, and there is always some Puritan douchebag telling them that they shouldn't or they're doing it wrong, or they're doing it with the wrong people, bla bla bla 'till the end of time.
