I suppose McCarthy-ism has had a lasting effect on Hollywood's desire to speak out against political wrongdoings. That said, viewership for the Academy Awards has been trending downward, year after year. Hollywood is an elite club, that up until a few years ago, people of colour were having a difficult time being recognized for their talents. I don't recall any sweeping groundswell of white actors calling for more diversity in their little club. Frankly, I find the whole thing to be an incredible bore, particularly when well-paid people who "pretend" for a living get up and espouse on politics. 

And by the way, no matter how repugnant an individual is, sucker punching them is an assault. Regardless if you think it deserving, funny or not.
