This one is an article from 2002 by Akilah Monifa published in the Miami Times.
It says simply that many games are perpetuating racial and gender stereotypes. There are a couple important stats: “four percent of African-American characters appeared as heroes… Black American female characters were also more likely than any other group to be victims of violence… Every one of the Latino characters was in sports games, usually baseball.” There are some rather disproportionate numbers too, such as Latinos who were shown “exhibiting physical harm and pain after an injury, such as colliding into a wall while trying to catch a pop fly.”
Baseball violence is for the most part comic mischief compared to any run-of-the-mill shooter, and I believe the author may be making a bit of a straw man argument here, but there are other statistics I’ve seen that seems to generally agree with the findings. I’d say it’s something that’s worth looking into.
