Just not Roman Catholicism...that's the difference.
If it's Rome you don't like, do you think you'd fare any better with Byzantine? Celtic? Syriac? Antiochene? Maronite? Coptic? Armenian? Syro-Malabar?
Go look up all the ancient churches that weren't Roman. Let me know if any of them look like where you go on Sunday.
Any Catholic Church in communion with Rome is one with the original Church.Some not called”Roman” are in communion.
