An Odd Contradiction between Leftist Arguments in Two Different Areas

I've recently been looking at some old Usenet debates on guns. I've noticed two claims by leftists:

1. If the topic is gun control, they will respond to claims that we need guns in case we need to overthrow the government by ridiculing the idea that people with mere assault weapons can stand up to tanks and bombs.
2. If the topic is anti-terrorist warfare, they will claim that “asymmetrical warfare” makes it possible for people with assault weapons to stand up to mere tanks and bombs.

I suspect that terrorists trying to set up a totalitarian regime don't want that many guns. (If they have guns, they might not want ammunition.) Guns make it too easy for the wannabee dictators to be overthrown in turn. That may be why they prefer suicide bombs.
