Lmao. Everyone has a right to free speech. Say whatever you want. However, free speech isn't a one way street. A large amount of people in this country have forgotten that. Don't be surprised when people react to your free speech with their own.
Also, I truly hope you're not going to defend his comments on COVID as a different viewpoint. That not a differing opinion, that's someone denying science. Spreading "fake news" about a deadly pandemic isn't an opinion; it's stupid at best and dangerous at worst. He was rightfully attacked over that idiotic tweet.
