One of the worst things government does is force people to be around, and deal with, those they'd rather not associate with.
It doesn't matter if their reasons are often stupid.
One of the most fundamental human rights is the right of association. If you don't want to be around certain people, for any reason, no one should force you to.
Apparently, many people don't want to be around others based on some accident of birth-- skin color, language spoken, or whether that person is Jewish. Other people-- smart people-- only discriminate based on what someone chooses to do.
I don't want to have any interactions with cops, tax collectors, government bureaucrats, or other career criminals. I don't care about any random factor about people that no one had any choice about. I shouldn't be forced to interact with those who choose archation, yet it's "illegal" for me to refuse their advances.
That's evil. Government did that.
