Some of the anti-Catholics actually claim to have friends who are Catholic. Either they are lying about having these friends or they don’t have a clue what friendship actually means.
I learned a lot that kinda deals with this from an exchange with some guy on some animal cruelty thread a few years back. It was the same argument of 'what's with you people? How sick are you to care about animals when there are [some horrific number] of babies killed each year?' I pointed out, civilly even (honest!) that instead of taking people to task on this thread, it might be a good place to recruit. Obviously they are compassionate people, and maybe they could be made to change their minds on abortion by exploiting our common points?
The guy literally laughed at me, mocking the idea that he would want "to change anyone's mind." So in his little world, the most important thing about saving babies was that everyone knew he wanted to save babies. If talking nice could help the unborn, well, that wasn't something he could be bothered with. It was all about him.
And so is it with a lot of the anti-Catholic hate. The true haters love to be the ones who prove they know better, regardless what any Catholic tells them about Catholicism. They build up their purity by dumping on us, mouth wide open and eyes and ears sealed shut. Facts be damned. Sad.
