People won't quit bad behaviors. All you can do is call them on it and point it out.

And risk being called a racist, or patriot, or christian, or ... american ?
That is the disconcerting thing about liberalism.
If any negative behavior requires human willpower or a moral framework to alleviate it, most conservatives will attempt to do just that, and falling short, will strive to do better.
Liberals on the other hand, have this perverse approach to everything from crime to sexual behavior, where they actually embrace damaging behavior and encourage it because they view it as outside the responsibility of human control.
For example, sex between young teens. Instead of discouraging it by pointing out the negative aspects of such activity, they assume humans are animals that are completely at the mercy of their baser instincts, and since the behavior cannot be controlled or suppressed (in their view) they actually encourage it and make it easier.
Same with crime. I swear, liberalism is a mental illness.
