Why are you doing a PhD - well, that could be meant in the "what do you want out of it?" way, or the "why the hell do you think you can do one?" way. The former is ok, the latter isn't.
The other three questions/statements are, IMO, disgraceful. Either your supervisor is on an ego trip to make himself feel good, or has no idea about other people's feelings, or is a ****. From the sounds of it, **** seems about right. If a supervisor of mine ssaid that to me, there'd be no way I could work effectively with him.
