Pro-Trump Republicans claim that the rioters were Antifa while at the same time claiming they were also normal visitors.
Those aren’t (usually) the same individuals, as far as I can tell. Republicans who weren’t there, or who were there but weren’t responsible for breaking and entering, say the rioters were antifa plants. Those who support the rioters full stop say they were peaceful patriots.
It’s infighting, not so much hypocrisy. The left and center tend to think of conservatives as lock-step Authoritarians™, but that’s really not the case. There comes a point where right-wing conspiracism collapses under its own weight because the theorists can’t agree on which alternate reality is actually correct.
