Thanks for the comprehensive comparison, Tom, where you copy individual incidents from one group from ...somewhere..
How about this....the chart below only goes through 2016...but according to the Anti Defamaiton League
the trend continues through 2019.
"The fact is right-wing extremists collectively have been responsible for more than 70 percent of the 427 extremist-related killings over the past 10 years, far outnumbering those committed by left-wing extremists or domestic Islamist extremists — even with the sharp rise of Islamist-extremist killings in the past five years."

In conlclusion it would appear people who wear MAGA hats are more likely to commit terrorism than people with towels on their head. But I'm not sure reducing people to a stereotype based upon that criteria is particularly intelligent.
