HR departments are often charged with helping overstressed workers release some of the stress and tension. That often means crappy pizza parties at the end of a quarter. Sometimes it means off-site parties with BBQ and beer. Sometimes it means renting out a movie theater. Sometimes it means giving funds to 'clubs' at the company to buy some craft alcohol, host a drag event, go play tennis, or anything else.

I don't understand what is political about a drag event. It's a form of performance a la theater, comedy, dance, etc. Can you explain what would bother you about drag queens being promoted? Perhaps drag performances disturb you for some personal reason but to another person a workplace craft whiskey club with a bit of funding from the company to buy a bottle once a month would be disturbing because of the life experience of having an alcoholic as a father or loved one. But I wouldn't expect every event a workplace to put on to appeal to every employee. If that is the goal that is how you end up with the pizza party and that's about it.
