“So how come no one cares if I am offended just because I am “white”?”
That is exactly why. A few years ago, my former workplace put up posters in the break room announcing the “celebration” of “gay pride month”. I complained to HR. Used all the buzzwords: offensive, violation of my religious principals, hostile workplace, etc, etc. I was told in no uncertain terms that if I didn’t let it go I would be required to undergo sensitivity training as a condition of my continued employment. Had my circumstances been different I might have told them to take a hike, but at the time opportunities for a guy my age were scarce. Where is all this “white privilege” I keep hearing about?
It's an entry in the liberal playbook. Reality doesn't apply.
