Vegetarian diet was considered the ideal for humanity--- Whether Judaism believes in this?

No, you are not a vegetarian, as you occasionally eat chicken. You could describe yourself either as flexitarian or pollotarian, or, if you also eat fish and/or seafood as pesco-pollotarian. However rather than any of these titles it is just better to state clearly that you don't eat mammalian meat, or that you eat a mostly vegetarian diet but are not a strict vegetarian.

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.
