Do not be deceived by this. Their intent is to create gulags here and "disappear" people who stand against their agenda. They describe us with the terminology of the violent institutionalized left as a means to try to divert attention away from their true goals and ideology.
Have no doubt: these leftist revolutionaries would be very happy to line people up along a pit and shoot them. In fact, they are dreaming of such a day.
In the pursuit of their goals, illegal aliens are just tools. Once their utility is gone, the leftist revolutionaries will discard them just as they discard anyone who does not advance their goal of absolute power.
I think most of these "revolutionaries" are useful idiots, who will also be in this line along the pit. They know not what they are doing, and how their actions will eventually allow the truly evil despots to eventually take over the movement and start the cleansing.
