No, it’s not bigotry to be against child molesters.
Come over to the good side.
Bigotry is implying that all priests are child molesters. All aren't, a majority aren't, a large minority aren't, and only a tiny minority are.
So yes, what you are preaching is bigotry. It's as much bigotry as if China had passed a law banning old people from Protestant churches, and I said, "Well, at least their savings will be safe from the money-grabbing hucksters behind the pulpit".
By the way, I saw nothing in the article about children being banned only from Catholic churches.
