tbh, I'm not sure why people shouldn't be allowed to have sex in the street. no one is saying you have to have these people over for dinner or hire them for a job. they can still be denied entrance to restaurants and generally shunned from polite society. all I'm saying is maybe they don't need to be locked up.

All of society is going to be a compromise. You represent one extreme just as the theoretical conservative uncle represents the other. Meeting somewhere in the middle is the only way to have a functional and healthy society. I think most people would agree that hardcore drug use in public is not desirable. Like I said, I think it's worth debating but don't be surprised when the end result is repeatedly in favor of suppressing behavior like that.
