If he doesn't know what the word "gay" means, then he didn't watch anything on television that made him announce this. Someone has said to him, "You are gay, just like your Uncle. "If he had never made such an announcement prior to visiting his aunt and cousins, then they are the likely source.
Does he like his aunt and cousins? Would he miss visiting them? Ask him.
If the answer is "no" now -- assuming that it was "yes" previously -- then they are probably teasing him. I don't think there is anything wrong with being gay, but I do think there is a lot wrong with teasing. Keep him away from them unless you know for sure that this will not recur.
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.
