How can I tell my uncle to stop abusing my family?

No hes just being a dick, taken his frustrations out on you. Don't feel bad. My dad loves me but use to do this to me.

If I had a dollar for every time he asked me am I that dumb...id be rich.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
