I'm actually going to agree with Cole World on this one. Society has gotten to the point where people's skin is too thin and being Politically Correct is so important that it stifles comedic creativity. Most comedians (particularly stand up comics) jokes are made of offensive, bigoted, and stereotypical content.
This has been going on for years but as Lange stated in the article, Social Media is to blame, not the joke. Think back to Eddie Murphy's stand up comic bit where he ripped into gay folk. He even used duragatory (and by today's standards) offensive name calling and everyone laughed including the gay community.
Today we have people who need to be coddled because of something taken out of context like this joke. If it isn't your type of humor then don't watch it. that was the rule of thumb back then.
Today it's "if it isn't your type of joke. Jump on twitter/Facbook start a flame war, get others like yourself to chime in, and see to it that the actor/comedian pays for this outrage."
I guess it's just the mark of the times.
