nfl kneeling

My English teacher wanted us to type a general controversial MLA essay and I chose the topic of the NFL kneeling. I have two opinions about these, I support those NFL players who kneel because they are practicing their freedom of speech but I also understand that it is disrespectful to disrespect those who have fought for this country. I was wondering if you can write a 3-5 page essay about this topic with resources and an annotated bilbiography.
