First, like all RCs you call people names when you have no facts. Anabaptists (literally: "re-baptizers") were derisively called that by Roman Catholics(sic) because they, the anabaptists, refused to accept the heresy of infant baptism practiced some then by RCs and a lot, much later. So, "heretics" more properly describes those that subscribe to this heresy - primarily RCs.
The "crime" of the early Baptists, the Christians of the First Century church of God of the Scripture, was they accepted the Scriptures (then written) as the sole authority for doctrine, faith and morals, unlike those apostate Baptists, that gradually developed into the sect called the Catholic(sic) church.
You state YOUR church "stamped out" these "heretics." Be honest, by "stamping out", you really mean tortured and murdered them - good "christians" that YOUR church claim to be - for their "crime" of disagreeing with YOUR church and the authority of its leaders (not yet "popes").
Independent Baptists of today are the literal descendants of these early Christians YOUR church(sic) is so proud of terrorizing!
There are none so blind as they who will not see, or so deaf that will not hear!
