That wasn't a neutral post about thalidomide, it was obviously flamewar fodder, and therefore rightly flagged.

Would you please stop posting like this now? If you keep up this flamewarry/offtopic stuff, we're going to have to ban you. Also, please stop hounding any particular user. That's not in the spirit of the site at all.
