Mr – It is perfectly simple why your post was deleted. If a user suddenly appears and poses a question (I didn’t see it, but I can imagine) that is bound to induce negative responses – or at least a big argument with everybody calling everybody else an Apikores – the Moderators will delete it.
Such discussions haven’t been allowed for quite some time (all real controversial issues were back in the good old days, see the ‘Controversial Issues’ thread, from the back page).
If you have posted for some time and are known not to be a troll, to use CR-Speak, and if the Moderators decide that there is no Kefira or anything that will cause Kefira in your post, THEN they will allow it.
So that, perfectly simply, is why they deleted your post.
