I'll take the word of real Founder James B. Taylor (the first Secretary of the Foreign Mission Board of the SBC) over the representations of the disgraced Ascol/Nettles outfit.
Writing in the 1850s, Taylor reported that:
"the view now generally adopted by the Baptists [is] that the atonement is general in its nature"
His Northern Baptist contemporary Edward Hiscox concurred, testifying about mid-1800s American Baptists:
"Though diversities of personal opinion in many cases may incline to either extreme, the 'general atonement' view is for the most part adopted, while the "particular atonement" doctrine is held by not a few."
