Every family member/friend that I have talked to that is a Trump supporter has the same response (which would be expected as a tenet of cult behavior)
1. Storming the Capitol was not a big deal, no different than any of the Antifa and BLM protests we have seen all year. I looked at the news coverage on Jan 7 and understand why they have this point of view, because OAN and Newsmax were not covering the Capitol insurrection, they were doing stories on Libs running business out of San Fran and how Dems were botching the vaccine rollout (I saved screenshots from that day).
2. When I confront that storming the US Capitol absolutely was a big deal, the uniform response is that it was a plot by Antifa and Pelosi. I ask for proof or evidence, and get blank stares.
It is pointless to argue with an irrational person, so I simply say they should question where they get their news from and that OAN/NewsMax/Stormfront or whoever they rely on for "real news" is not reliable, and they should realize that after yes, indeed, Biden did get inaugurated despite what they have been told.
