[Yuki Maru Hoshi]

There are leftist terror cells that are very pro 2nd amendment. A lot of ex military members and they basically are slowly building up a small militia of folk that support their cause. One was an offshoot of Antifa. So it's only a matter of time. These are people that are not afraid and weren't concerned at all at the time they were being documented with these views and were keen to show off how militarized they were and what they could be capable of.

Edit: At the time they were claimimg to be arming up in defense of their community (including LGBT), which is the point of a militia, but it's been made clearer over the years that there is a bit more going than just self defense...
