The Moderators are 100% certain that bubka is Joseph. Not only from this post, which is a pretty good proof, but from other bubka posts as well. Many of which saying identical things said by various other Joseph personas during the years.
In other words, please dont think that we assume it is Joseph solely cause someone dug up an old post.
We have spoken to him privately, but to no avail. The only recourse is to out him publicly. If nothing else, we are trying to show all those who come to the CR (even the non Jews who come for a look), that these are the beliefs of a very sick and twisted individual who chooses which parts of the Torah he wishes to portray, and which he chooses to turn a blind eye towards.
