Christians why do a lot of you?

Spend your life hating Catholicism? Don't you realize that you are giving into the devil when you go around hating another religion? Regardless of what Catholicism did or didn't do in your eyes or for what it stands for, you really should look past all of that and find some peace in your hearts. Jesus said to forgive and love your enemies. So why is there so much Catholic hatred for whenever a question of Catholicism comes up? Especially when the person asking directs their question to or about Catholics?
