If he accuses me directly and namely he must bear my defense on his thread if he's honest

Yeah, he probably should have allowed you to state your case, but he didn't and there isn't anything left for you to do in that thread.
Instead of starting a thread like this one, calling for Little Mouse to get tagged, it might have been a better idea to start a thread in Reputation referencing LM's thread and laying down your own argument as to why his accusations aren't true. This shit happens all the time on bitcointalk. IMO, I don't think anything Little Mouse did in that thread makes him worthy of a neg.
Whatever you said in my thread was off topic in my opinion and that's why I had deleted your post. I did not created self moderated thread to censor anything.
The post OP quoted that was deleted didn't look that off-topic to me, and given the fact that you outright accused him of being an alt of someone, I probably would have let it be. Just my 2 cents.
Ok I will change the title then.
