Some people reflexively hate “Rome” ... they’re simply following their programming. It’s sad, really. Many of them are otherwise intelligent people. On this one topic, they’re nuts.
Once you realize some major tenants the Roman Church teaches are not scripturally sound, and Boarderline, if not entirely heretical, You can see why people despise the current form of the Roman Church.
When Mormanism and the Jehovah’s witnesses(which I am positive no one here will argue against them being heretics) are in all honestly, more scripturally sound(not by much) then the current Roman Church, there is a problem.
