Extremist views on racism strangely coalesce when you reach the edges of the debate.
Regardless of the the colour of a persons skin, the more extreme their particular view on race (whichever race), the more in common they have with their counterparts. Sort of a racist code of diametric agreement. The extremes of the brotherhood feel they are, or have been, or will be the victims. Both feel to have been oppressed or held back or overlooked by those in power. Invaded, discriminated against and the interlopers should be kicked out.
And luckily, the web allows us all to be on our guard. To say no. Things can be different.
