I agree with your general thrust, but I disagree with your conclusion.
We need to say when things are wrong. It's vital. And right now what the right in America is doing is wrong. I'm not some absolutist left-winger. I once had a firearms license here in Canada. Though I'm a happy Liberal Party of Canada member, I've voted for Conservatives in the past and I'm open to doing so in the future.
I do not have intolerance of other viewpoints. I actively seek out a broad range of views. What I have intolerance for is violence and calls to violence and lies. If that's the charge against me I happily accept whatever verdict you or anyone else will levy against me. The truth matters. Peace matters. I am unwilling to let these half truths go by without comment or rebuke.
