You've greatly misunderstood me. Some of my closest friends are black, and I have the utmost respect for people who are black and any other ethnicity. Nor am I saying black people are orks, savages, or that people who listen to rap are, I like rap myself, which is why I thought of this in the first place. And if you think about it before immediately branding me a racist, I made a valid point. Orks do wear "colors" like people in gangs do, they have their own symbols, dress, and all around culture. HavenDan is very correct, it is partially inspired by people who are "posers" but also by actual gangs. And remember, I never said "black people" you're wrong for assuming that, and while I did say the hip hop culture, many other people, including white people, are part of that. Music know no race or color, black, brown, yellow, white, and now green. Lets remember Dr. King, shall we?
Now then, I'm new to Orks, so could anyone offer me advice on what units would be good for an infantry heavy army?
