Ok, I'm not that sorry to say it, honestly; Islam is the Mormonism of the Abrahamic religious triad, except its founder is even more of a monstrous pedo.
All the same, I appreciate the way of thinking: "Let's adopt the hardline traditionalist religion; that'll show the Left!"
Except, it won't. The power that Islam currently holds is completely dependent on the hyper-hypocritical Leftist doctrine of Intersectionality.
A bunch of lily-whites start praying to Mecca, and Islam loses the protective status it has as a 'po' widdle oppressed brown people religion' and instantly becomes the target of every wailing blue hair from here to Saudi Arabia. Or, at the very least they might try to differentiate between "White" Islam and "Brown" Islam, which would still cause some of the later to be targeted by the smoothest brains, and would result in some wrathful retaliation, but I digress.
Either Christianity is reclaimed and goes full Crusade mode, or Populism becomes the de facto religion of the Right.
Unless the Caliphate comes into full prominence, in which case, hand me my Pulwar and let me grow out a shitty beard.
You guys need to read Submission. While I'm not on the Islamo bandwagon, it makes some good points about the fight against secularism. Essentially the core point being that western ideologies failed to fight and beat the secular monster while it rose. The essential conclusion was that as bad as Islam may be, if you hate secularism, Islam may be the right vehicle to fight against it effectively. I won't be becoming a Muslim or allying with them in my lifetime, but Islamic radicals are SJWs with explosions and more force, so I can see how they could actually win a war against secularists purely based on fear.
