Protestants as far as I'm able to tell are spiritual brethren with Catholics, even according to Catholic creed. They share just about all the same tenents of faith, with only two real disagreement all regarding the authority of the pope and tradition. A properly baptised protestant, doesn't have to get a new baptism when he enters the catholic church.
Yet discussions about protestantism are made in the same are where you'd discuss Islam or Mormonism. How come?
I also did a quick counting, and a full 17% of the past 240 thread openers were about, aimed at, or involved protestants. That's not even couting the output on Eastern Orthodox Christians. Wouldn't it make sense to have a second subforum for Eastern Orthodox and protestant Christians, since at the end of the day, both catholics, protestants and eastern orthodox Christians respect each other as such?
