I'm Irish, male and over 35. It doesn't affect my reading experience but since my kids started reading comics I've become more critical. My kids are mixed [wife is Nigerian] so race and representation has become more of an issue.
My kids get excited when they see brown people in comics or on TV. My daughter always comments whenever she see's little girls with curls in media. I'd like images like that to be the norm rather than such an exception that she's compelled to comment.
