That's quite a tirade, Rob.
Yeah, Deus Vult is PC... Anyway, I'm not sure what's serious there and what's just simple pouting.
DV is fine for crusading. If anything, the ability to force-vassalize infidel leaders, pagan or Muslim, is fantastic, and the negotiation with Muslims and pagans does change the tendency to see a Moorish Scotland (not that it's impossible now, of course). The automatic annexation of original CK was really sloppy, in my opinion.
Now, the thing about crusading is that it costs money. But wasn't that the way in CK to begin with? War was always expensive. Nothing PC about that. It's factual. Don't play Victoria. It'd drive you to suicide.
I can free up several thousand crusaders to ship them to the Holy Land (from Denmark, mind you) and still net a few dozen gold a month. I have only one king title, but I've managed things very well.
And frankly, if you're crusading with a county, you're missing the point. Better to pick on Sicily or the pagan Baltic (as I did with the County of Sjaelland). If DV won't let you take on the K of Egypt as a one-prov count, I'm not sure what the problem is.
In any case, I have to agree with Rob, but not in a way he intended. It really is about this:
"You start, you shore up your finances, build an army, ensure the Church knows it's place, have a son or two then, when your land border is secure against the French, you head for the Holy Land to forge a Kingdom of Heaven...."
That's the way to do it, and that's why DV rocks. It is the true heir of CK and sharpens the game in many important ways.
