No it's hurtful.
The fact someone is nasty enough to tell you, is disturbing.
I don't believe in curses, but I would find it disturbing and hurtful if someone aimed one at me.

It's the act.
I was disturbed when animal rights people targeted a neighbour of mine and sent poisonous letters around to all us neighbours and the police were involved, they do threaten people's lives and families and that can be disturbing.

You can get it from door to door and street evangelists now and again.
