I'm not talking about religious belief systems, I am talking about the post-modernist left. They have a choice in killing or not killing non-believers. Mooslims do not. Jihad is the core tenet of their faith.
Also, while the average post-modernist may have the same zeal of jihadis, they do not have the same level of education as jihadis. Don't believe me? Watch all of the riot footage you can, listen to them speak and ask yourself, "Do these kids know American history, world history or biology? What about political history? Now let's pick a country, say Iran. Now ask them the same questions. Now be honest, who do you think would be more knowledgeable?
That has been done btw.
