> Who defines what is culturally OK?

I define what's OK to me. I am able (and legally allowed) to choose what my browser displays to me, so I use browser extensions to control my (and only my) experience of the web. I do not hurt anybody and I do not impinge on anyone's rights. I resent attempts at moral preaching aimed to make me feel guilty, especially when it's in defense of powerful entities that I find reprehensible and who do impinge on my life in ways that I object to.

My local bus company does not do that.
