why dump Facebook?

I began a Facebook account after starting this blog. Now, years later I'm done with Facebook. Why? I posted a question. Are Americans STUPID enough to believe the lie, if it was a lie, that COVID is even a crisis at all? And was the lie created to get rid of trump? Did so many Americans cooperate with that? And Facebook blocked me for a while. An unbelievable idea on their part to PUNish you? And their reason was using the WORD stupid?  Liars. They didn't want me to say that I thought attempts were being made to destroy Trump. Unreal. Will we tolerate such tyranny????
