Islamic conversions are possible. I suspect you'll see more Muslims simply due to immigration and birth rates though. Though who knows.

The churches in the US have kind of fumbled the ball with the generational passing of the torch really. I think it's simply due to corruption and the churches trying to function more like a business than an organic reflection of the communities they are in. I mean goddamn have you been into one of those McChurch non-denominationally Baptist megaplexes? It's like they skipped the chapter where Jesus went ape shit on all the people selling things in the temple. Like good God you're going to advertise your fucking bookstore during the sermon? And call the cops of me for loudly condemning you mid service? WWJD? Oh wait I have to pay to use that shit right? Just like the "New Revised Millennium" translation or whatever the fuck it's called I have to pay zondervision publishing house to quote from? Really hate Christianity x Capitalism just feels scummy as shit. But I'm a milk or coffee kind of guy anyway either is fine on it's own but don't you fucking mix them and ruin both.

Maybe the Muslims are on to something actually. Though I suspect there's big money to be had there too. Any Muslims here wanna chime in? I kinda suspect the Hajj has become super commercialized judging by all the construction going on in Mecca. But it is Saudi Arabia and I'm not allowed to go since I'm a filthy Goyim anyway so maybe it's just all oil money?
