Replying to Dress codes

I was getting lunch at a spot downtown that is a common nightclub on the evenings and weekends. On the way out there was a sign stating the dress code. Won't post it here, but to summarize:
-Hats to be worn forwards only
-No doo rags or hoods
-No visible tattoos above the neck
-No excessive display of jewelry
-No excessively baggy clothes

With this big movement lately in regards to racism and the equal treatment of everybody (how people get f'd over for not serving homosexuals), do you think dress codes should/will ever be targeted? Call me racist, but it seems like the above mentioned dress code does target certain demographics whether gang related or cultural.
