I said I know what most of the Trump supporters who post on Breitbart say in their posts. I never said I know what they think except as I said, "most want to see American great again." You'll be a lot less upset about what people think of Trump supporters if you follow what they day. I did not disparage Trump supporters in general. I only quoted what I have seen them post.
You are trying to say I am a hypocrite. I asked how you know what is in the mind of those against Trump and you came back (incorrectly) saying that I was claiming to know what is in the mind of Trump supporters. 
You did not answer my question: How do you know what is in the mind of a person who has criticized Trump or his supporters?
