Never attribute to malice that which can be adequately explained by stupidity.
For THIS to be anything but malice is too hard to believe. The charge is obstruction - the method - he wouldn't stop talking. The cause - he wore an NRA t-shirt.
I suspect this is what Stalin's USSR would look like if it had started off with a Constitution - It would have ended up in the same place, it just would have taken a few years longer. Exercising his first amendment rights - by showing silent support for the NRA is tantamount to terrorism - which apparently they considered charging him with.
Yes the progressives really do think the NRA is a terrorist organization.
