Calvinism isn’t Southern Baptist. And Calvin himself was a tyrant who murdered someone who challenged his interpretation. Thats about as far from Baptist as i can imagine.
You don’t know much about the SBC or Calvin.
Historically baptists were “reformed’

No where in scripture do we fine “free will” or “ altar calls “
There is disagreement on Calvins roll in the death of a heretic..but i would remind you that david killed a man to cover his sin..and he was called a man after Gods own heart..
