He sounds like a bit of an easily defeated coward to me, if that tweet is real. "Oh, poor me...I will stop telling the truth to people because people didn't accept what I said. Waaaaa!" The truth is the truth and if a real doctor is so scared and/or daunted by morons, well, that's just sad. If that tweet is real, then clearly he is no champion of the truth if a wee bit of adversity shuts him down so easily.
