Just from personal experience, Catholics are better at this. Other religions often consider religious instruction a charitable function. Catholics just help you, and you're moved into wanting religious instruction.

When I would go to St. Vincent's as a homeless teenager, the only indication that I wasn't receiving services in some government office was the foot-high cross on the back wall. I don't remember a single mention of religion. Plenty of Protestant churches would make you sit through a service before feeding you.

edit: that's what I get for not reading the article before commenting. This is just fraudulent. It's a charity doing Zionist things for Jewish youth. Most non-Jewish people wouldn't donate to a kids' charity that wouldn't do a thing for their children if their children were needy. The only need it's attending to even in Jewish children is the "need" to love Israel and not enter into interfaith relationships.
