Though it's true Luther married a nun and helped nuns leave their convents I don't think statements like this are productive in getting people to convert. I'm pretty sure Dr. E Michael Jones, whom I greatly respect, called Protestantism a looting operation, whether that was true from the 16th-19th centuries I wouldn't use it as a blanket statement today. I have a baptist friend whose church almost couldn't be more plain* and they're very generous towards their communities.Have you read the Enslaved Will? Luther and his merry group of degenerates 'liberated' nuns so they could experience sexual 'freedom', which often meant being taken advantage of. Look it up.
He was a wild pimp who couldn't control his passions, and on the totem pole of religious founders, ranks slightly above Mohammed.
We are all entitled to our opinions, and mine is that Protestantism is a joke.
*This point actually came up in a debate I had with him as he took offense to how Orthodox churches are so finely decorated.
