The major problem is as a writer as well, I do not want to impose the story on a creator. If someone does not want to write a story about a person of colour, well okay. Marvel though can choose which stories they want to develop. They choose stories where every black male is a side kick in the military and women are usually love interests (Even when these relationship do not exist in the comics...).
Speaking truthfully GotG gets a pass for me (though I am not sure why aliens always abduct people from developed nations as opposed to some place where the abducted won't be noticed...) Spiritually the movie is about diversity and its strengths.
