No, PC has gone way to far. It's intellectually dishonest to pretend that when someone says something offensive and get fired, that it's some sort of social condemnation. Look at the mozilla guy. Most people, even most mozilla employees, don't care. He was fired because an extremely vocal minority found a victim no one wanted to stand up for. Shitlibs love to create false dichotomies like this. Fire the CEO or you are a homophobe!! Maybe I don't want him fire and I'm not a homophobe? It's not social condemnation, it's a scorched earth tactic.
Don't worry though, these people have no honor. In due time they always end up going after the very shitlibs who supported them in the beginning. Just look at Colbert.
