That looks to me not so much like “The enemy does X, therefore we’re justified in doing the same to them” but “The enemy does X, therefore no one can object to our doing the same to them without hypocrisy”. I think Vox Day and his pals would want NFL players fired for “disrespecting the flag” (etc., etc., etc.) even if no one were doing anything of the sort to rightists.
(I’m sure there is a lot of “they did X to us, so we can do X to them” thinking going on, though, on all sides. It’s a very standard social failure mode and tends to lead to prolonged escalation.)
