No, they they think the 1st amendment sucks, and now more than ever people need to be ready to shoot people that they disagree with politically. That's the only honest interpretation of the message.
But, this is going to end up just like the arguments about when Trump said that the 2nd Amendment people could do something about Hilary if she got elected. It was indisputably a, "wink wink nudge nudge know what I mean" statement implying that political violence is acceptable if it's against enemies. This is identical.
