1) I posted something a long the lines of "Hitler never actually wanted to kill the jews" or something along those lines, which I supported with ample evidence and wanted a healthy debate on the topic. It got deleted for no reason.
2) I asked the mods before why they deleted my thread on a couple of other things with no reply and it was very constructive, but I got annoyed as nothing was being done. And now I have a warning and feel this is highly unjust.
