How easy it is for the modern libral to categorize people simply by the parties they join. While there are white supremists in Afriforum, it simply does not mean that all people in Afriforum are racist white supremists, just like all ANC members are not corrupt thieves, but there are (seemingly quite a few) corrupt thieves in the ANC, yet for some funny reason I dont hear the liberals say that...it is considered racist to think along those lines.
Couple that with the shaming that is actively applied to anyone that is even remotely connected to Afriforum, being Afrikaans and white seems to be enough.
As we have seen by the voting blunders in the world, people will vote for parties that represent their worries, in spite of some of the others within the party.
So calling people that worry about themselves and their immediate friends and family racists, but only when its politically correct to do so, is the reason why people are moving away from the standard parties that have failed us.
