Should you give someone a not helpfull vote just because you don't like thier opinion?

No, but I'm sure that it happens all the time, and people probably give helpful votes because they are annoyed that someone else gave an unhelpful vote.

Giving a not helpful vote is due to two reasons one: the answer reported I not correct. In this case you can surely give an not helpful vote. Two: you don't like the person, well in this case, if answer given is correct to context.

You don't have to give an not helpful vote. But if you really hate that person then go on you can give a not helpful vote. Mahalo doesn't screw you, if you do it.

Only the person who is submitting the question will decide on the correct answer.

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.
