I don't think if people belong to a different branch of the church it automatically implies that they know less... Just because the catholic branch was the official one or the oldest (which it isn't) christian branch on earth. And at the time the protestants came around they really had some righteous causes. I can't imagine as you like to profile yourself as a rebel that you are against some of their stances. Not all naturally, personally I can see why they for instance wanted to get rid of the pictures and statues in the churches but it's still a shame they destroyed that stuff. But yeah, if you look into why they rebelled against the catholic church exactly they had a point. The church was at a height of abusing their power and the bit of power that the people felt they had was eventually used. Can't really blame them. And the catholic church stood always as one universal church? Is that why there were once 3 popes at a time?
