It’s a problem of propaganda. All the mass media is owned by a few wealthy interests. A lot of people only get information from mass media. Media which regularly gave a seditious tractor like trump undue respect and deference for fear of 'losing access". When they don’t treat him with the disdain and animosity he rightly deserves. People question whether what he did was actually that unusual or even bad.

Yes they saw what happened January 6th, but most of the media doesn’t even bother to mention it much now. So it must not have been that big of a deal right? All a bunch of overblown hyperbole and bluster like Republicans accusations against Democrats. So they just “both sides” it all. Handwaving it away, thinking themselves above it and superior. Only bothering to latch on to talking points they like. Which only makes things worse seeing how bad Democrats are at playing the media compared to republicans.
