I am a racist person who hates niggers and such. However, a lot of the people on stormfag.org are trash. Why are racist organizations so desperate that they will let in any meth junkie who hates niggers? It makes us sophisticated racists look bad. Where are all the racist sites with upstanding white citizens?

Like Asians take rice (which is one of the factors affecting their physical differences) as their diets probably due to one or number of wanker though its a good diet for number of reasons and everyone follows because the majority saw that benefits.
