My company is in the middle of a big diversity campaign right now. There's mild pressure to participate, the department gets points for participation with the area with the most diversity points getting a plaque or something, but it's not overbearing and it doesn't count against me if I don't. And all hyperbole aside, I doubt that it's much different at Home Depot. I doubt that this guy is forced to do much of anything except to live with the fact that his company has an "LGBT Month". And that bothers him. Well, if it bothers him that much then quit. Go to another big-box store that doesn't observe it and he should be happy.
That mentality is quite the antithesis of what is routinely expressed here on FR. Would you suggest that people of moral courage keep changing jobs, in perpetuity? Would you not tire of running?
I applaud this man for taking the moral stand against the evil infiltrating our lives. Stand for something or fall for anything.
