If by "don't like" you mean "won't date" then no, of course that is not sexist. It is a preference and you cannot help what you are not attracted to. If by "don't like" you mean you would treat her poorly and with disdain, it's still not sexist per se, but it is somewhat discriminatory.
But of course, certain women will still call it sexist. Anything that a man does that is not what those particular women want him to do is sexist in their minds.
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.
