The SBC is not a Protestant denomination or denomination of any kind. It is an association that independent churches can join or leave at any time.
So tell me, just how does that affect their ability to drive out sexual predators from their pulpits? What you write is a distinction without a difference. Because they don't have an ecclesiastical hierarchy doesn't absolve them of collectively rooting out the rot within their “independent churches." Putting forth "repentance" as a solution is both laughable and criminal, and you should be ashamed to have anything to do with any "independent church" that seeks to hide criminal behavior of any kind, but particularly sexual abuse. I don't know how your God regards this stuff, but mine is dead set against it.
The last Church I attended with my family before leaving for the Marines had a youth pastor become involved with one of the teenaged girls about six or seven years after I left home. They made sure the guy was arrested and supported the girl and her family. They were a member of the Southern Baptist Association as well.
Ultimately that church decided to disband and join other churches because the name had been tarnished, and it's not about a building anyway. The church is the people who follow Christ, not a building nor the group of people worshipping at some specific building alone.
Any Christian church that is not Catholic is considered ‘Protestant’ as in Protesting against the Catholic version of Christian worship.
