For all your condescension, it’s nice to see you finally get with the program.
We’ve been telling Catholics for years now that there are not 30,000 different denominations of Protestantism, but I guess until they see it themselves, there’s just no talking to them.
Also, there is no longer such a thing as "Protestantism" -- the Protestant groups are the Anglicans, Lutherans, Presbyterians/Reformed and Methodists
All other groups have split from these and are in varying stages of being Christian like the Assemblies of God, to not being Christian like Jehovah's Witnesses etc. -- as I pointed out, there are Christian and non-Christians groups who either club themselves under the "P" or "E" term or are derived from it -- as the aforementioned Seventh Day Adventists (Satan as Jesus' brother, Jesus as Archangel Michael, etc) and Oneness Pentecostals (rejection of the Trinity etc) and your groups etc. -- there is disagreement on the fundamental nature of God, hence the dogmas are utterly distinct, so cannot be clubbed under one "P" or even "E" term
Even amongthe Adventists, etc. there are various denominations - some divided on dogma, most on region etc. -- so the 20,000 number still holds as the number of denominations under the wide non-orthodoxy umbrella, but the number of different groups based on core dogma seems to be just about 2 to 3 dozen imho.
