you have an odd definition of fact. I did not see any facts in that link about numbers of incidents of either side.

The fact that the Trump supporter was beaten with a tire iron by some left wing loony liberal is well documented. It is also a fact that if there were incidents of violence by conservatives outside of Clinton events they would be reported in the New York times and take up most of the time on MSNBC, CNN, NBC, ABC and CBS. So far, I have not seen any such reports.
