Annoyed girl

I am in school (under the age of 16) (don’t want to give out my age) and for school we have to write an argument paper. I said i wan tmine to be on sexism in america and how its still a thing, the boy next to me told me i was ungrateful for living in america and need to stop seeking for attention. I am very grateful first of for living where i do and very annoyed that he thinks girls pretend all of this stuff for attention. I want to change all of there views hopefully with this paper.
