I don't think it's bad that the president did. I think it's more his reasons for attending that I don't like.
For our current president, everything is transactional. Everything is about trying to sell something, his own image, etc. So him appearing isn't because he actually cares about wrestling. It's because he wants to sell the image of himself as some kind of tough guy who represents the values and ideals of wrestling. Keep in mind he's a guy who was born rich, has never had to work a real job, and was handed everything in life.
Whereas other presidents we've had, maybe I don't like their politics, but they don't come across as disingenuous pandering narcissists. Like if George Bush went while he was president, I wouldn't have a negative view of it. But somebody who privately has disdain for non rich people? F--- him.
