There was a time when one could have a somewhat reason-able exchange with you, but that has now passed. Resorting to attacking Luther as if we follow him as a pope, and having Luther and Kathrina driven by sexual so that they snuck out in a fish barrel and whose marriage was no different than homosexual marriage, because you must defend the church they dissented from - which was a church that ordained known sexual active priests (and was rife with such) and is guilty of spiritual idolatry - places you in league with cultists who are bound to do the same due to their sola ecclesia basis.
I know you don't. I believe that the so-called reformation has been a disaster for the Western civilization and the low morals of the founding fathers of Protestantism bear me out in this conviction. The arguments in defense of Luther indeed at times are the same that could be used, and are used to justify gay "marriage", polygamy, bestiality or what have you. In all of these perversions the perverse side argues that freedom to marry cannot have a constraint. Further, gay "marriage" is very much the last nail driven in the coffin of our civilization, so the regression from Luther's shenanigans to today's bathhouse is rather a straight line. If that is unreasonable to you, I don't see how I can make it any plainer.
