Why do you say that? Are you brainwashed by Catholic haters?
Assuming that your statements infers that there are posters here that post hate towards Catholics (re individual posters who are Catholic) that is not possible, as they would be kicked out of the RF and FR also if that attitude is kept up. That's been my experience of observations.
Also, Catholics that post hate towards Christians are also restricted from posting.
Just a little clarity here.
If you have ever followed any of the Mormon threads on FR, you will see that many Mormons were banned for hating Christians for the mere act of posting truths about their false un Godly belief system
