Also Mechaman in regards to this:
To properly understand why a lot of Catholics were so reactionary against converts, you would have to know about the struggles they faced in a strongly Protestant society that was prejudiced against them.
Isn't that just basically the same type of prejudice but in the opposite direction? Sounds like two wrongs to me, not an appropriate reaction.
If you really think that you need to come back with a basic comprehension of coalition politics. For a modern-day equivalent, think of a "gay republican" circa-2004 when Bush was on his anti-gay crusade.
