they were totally different.
The left one cites actual examples and real organizations.
The right one, it trashes everything and everyone on the right generally.
very very different
You don’t have to look far to find actual concrete examples of violent leftists, and leftist home-grown terrorists. Look at almost any leftist demonstration (anti-war, pro-abortion, whatever), and you see a cauldron of violence waiting for the slightest trigger to erupt. And leftist terrorists have been active since long before 9-11.
OTOH, the “warning” about right-wing groups is all hypothetical, and there isn’t a single concrete example of a right-wing terrorist, nor of right-wing groups erupting into spontaneous violence.
