It doesn't seem that cultural differences between Catholics and Protestants were that big. Economic ones, true. Urban areas where police wouldn't go unless in groups. Terrorist/criminal organizations which administered their own law, judgements, and punishments. Political corruption. Seen by many as completely non-hire-able. The cultural gap wasn't religiously comprised, but the gulf was about as large. There was even also talk of the religious dogma of the immigrant group being incompatible with national sovereignty.
