More conservatives than liberals understand it, but does that mean conservatives should reject all liberals as allies? It doesn't make any sense. More brown haired people than blonds understand that Islam is a threat. Should blonds be rejected, ridiculed, or categorically dismissed because some blonds don't get it? Too many counterjihad information sources are also counterliberal, insulting and alienating liberals from this important cause.
Not all liberals are part of the problem. And some conservatives are. Let's not divide ourselves that way. It only serves the enemy. Let's aim for unity against this shared threat.
As Bill Warner recently said in an introduction to his Politics of Extinction video:
In a war you don’t need friends, you need allies. This distinction is important, because you have to like a friend, but you don’t need to like an ally. Under the threat of annihilation we need to see that all Kafirs are in the same boat. All of those threatened with extinction are Kafirs. Politics makes strange bedfellows, so atheist, Protestant, Buddhist and every other flavor of Kafir must work together to survive.
In Muhammad's day, his enemies didn't unite against the Muslims while they could. They squabbled with each other and Muhammad added rumors to help them distrust one another, allowing the Muslims (who were far outnumbered) to defeat the non-Muslims. We should avoid a repetition of history. We should unite against the Islamic ideology, and we should do it now.
