Warning: Do not watch the video above while drinking any liquid, lest you choke.
There are many arguments that those who claim the Radical Reformation (as versus the Reformation) use to deny historic Christian practice. But, as the video above points out, there is a whole set of arguments that are illogical, to say the least.
Because the video is Lutheran, I do not agree with all of its points. But, I certainly agree with many of what it says.
