I like Wiki too ! And I encourage everyone to donate a few bucks to their annual fundraising event. But I digress..
As I've made the point many times in recent days "Mass Shootings" is not synonymous with "Terrorism".
Wiki also has a comprehensive list of terrorist attacks in the United States going all the way back to the 50's....and lists them by the motivating ideology.

Since our current president has taken office there have been 14 confirmed acts of domestic terrorism on US soil:
11 - motivated by neo-nazi, right wing ideologies
1 - motivated by left wing lunatic ideology
2 - motivated by Extremist Islam
Among the 11 right wing acts noted is the recent El Paso shooting that people on this board try to falsely conflate with street crime. But I'm sure that wasn't the purpose of this thread, right? I would opine DonDiego's statisitcs make a pretty solid argument for gun control.
