**If** what you say is true, and **if** the Southern Baptists were all perfect, there would still be almost twice as many Catholics as Southern Baptists.
Well yes, that is certainly possible... and may very well be the case.
As a Catholic though, I really don't know much about the Southern Baptist denomination- so for me, I couldn't speak to that.
I just know the 70 million Catholics number that gets bandied about
is wishfully inflated, and needs to be nuanced when mentioned.
(At the same time though, I do wish that 70 million number was accurate.)
