Well it also shows white communautarism is forbidden for some reasons, while black/asian/latino etc communautarisms are authorized and even encouraged.
Obviously he's not going anywhere right now with this, but it might change in some decades. Whites will feel the need to (re)build their own communities based on their skin color as the number of colored people increases tenfold as years pass.
Let's not fool outselves, of course blacks indians latinos arabs asian stick together mainly because they recognized themselves based on their physical traits and skin color FIRST.
The funny is also that if there's some racial mixity taking place, it's far from being a massive trend, people no matter what you do stick massively to their owns.
No matter how many fake ads TV broadcasts every single minute promoting scripted multiculturalism between fictional characters, people from different cultures and with different skin colors do not blend together in real life, it's exactly the oposite in fact: they stick more and more to their owns and feel the need to strenghten, rebuild communities - thru networks , internet ones for example- that are reassuring and empowering for em and the development of their identity.
