As far as basic basic basic theology goes, one of the biggest stumbling point is the question of ultimate authority. Catholics put the Pope above the Bible. Protestants don't.
You're using very loaded language in your posts, though you may not realize it.
One of the defining characteristics of almost all Protestant denominations since Luther is rejection of the authority of the Pope. (I'm tempted to throw in a Dreaded Car Analogy here, but I don't think it's necessary.)
In a real sense, all Christian denominations ultimately put their leadership "above" the Bible even if they claim that the Bible is the inerrant word of God. They pick and choose what to stress and what to downplay. Baptists emphasize the importance of baptism more than Lutherans; etc. All religions that rely on sacred texts also rely on authorities to interpret them. The Southern Baptists have a convention which comes up with pronouncements on various religious and social topics. They have had leaders that say things like "women should submit to their husbands".

Is a SB who is devout putting their leadership "above" the Bible?
Again, see for yourself what Catholics believe and practice in Mass. Don't take the word of critics or those who have left that church - too often they have an agenda of making Catholics look bad.
