One reason I think the Catholic church in the US is very pro immigration, just means more pro-life catholic Americans. We can only expect the pro-life movement to gain power with more immigration. I notice the catholic church seems to be taking a more aggressive approach lately. Scranton's bishop Martino keeps threatening to bar sen.Casey from communion for a recent pro choice vote even though Casey is largely pro-life. Also threatening some local catholic college for having gay rights speaker etc. Threatening to have them remove any claims they make of being a catholic university. I'm not catholic bashing btw just observing a trend.
