Wikipedia is wrong. I hope you realize that Wikipedia is controlled by ungodly people.
There are so many flavors of baptist in existence, you can't possibly trust a user generated document from users that don't know any better and that is controlled by ungodly people. Yet, here you are. There are many if not the majority of IFBs that reject such claims. They believe they can trace their heritage all the way back to the preaching of the Kingdom with John THE Baptist.
It is difficult to deal with inexperienced people like yourself. If you even had a rudimentary understand of the topic, you know better.... but here you are present nonsense as fact.
I don't care what someone does today that call themselves Christian. I don't judge the term based on their actions. I judge the term based upon Scripture. I see that you could care less what the Scripture teaches. Peter said to glorify God because you are a Christian. Yet, here you are. Too ashamed to settle for what Peter said because some looney tunes person did something bad that claimed to be one.
Well. Apply the same logic to "Baptist". There have been plenty of sorry, worthless baptist that have repeatedly sinned against God. By all means. Take your own standard and apply it equally. Reject the name.
