Protestants tend to have a sense of individualism Catholics seem to find disagreeable. I don't think Protestants generally bear any malice towards Catholics but we don't care for the heirarchy and bureaucracy. Ironically it's what brought a lot of people to this land from Europe to start with.
As a Catholic, I have no problem with that. If you did like the bureaucracy, you might be Catholic. Maybe not but the mods rule of avoiding pronouns easily confused such as “you” which can be both singular, (You worship idols) and plural (You [as in the Catholic church] worship idols) has gone a long way to toning things down.
