YS,
“Because anyone can easily start mentioning moshiach nonsense and there we go again…”
I think it will depend on the topic, – if you will just mention Tanya regarding “Beninim” etc and keep the controversial topics out, you should not have an issue. (There are already other threads out there for bashing.. as we speak.)
Also, if you will name it “Chabad” that too will attract the bashers as well…
Moreover, I think you always have an option of closing a thread..
