Here is a very simple way to de-brainwash a Liberal and to get them thinking about their belief system.
We are redpilled but we also have to hide our power. We are always afraid of being known as racist (and losing our careers and other consequences).
White Liberals on the other hand are not afraid of this. Its not because they aren't aware of how "bad" racism is, it is just that they cannot fathom themselves being racist. Therefore they never consider what would happen if it was them who was viewed as a racist. They don't think about it. They just loyally follow anti-racism.
Don't try to use the fear of being called racist to convince them that their non-White "allies" are not actually their friends. That won't work. They will just think you are using guilt to trick them.
Instead reverse the logic. Ask them a simple question.
>"Have you ever been REWARDED for NOT being racist?"
They will not see that coming, and I can guarantee you, it will get them thinking about how much they are willing to defend a value that they haven't even considered had a finite value. To them, defending anti-racism is like an unspoken virtue. If you have that value, then you are on the "good side". If you don't have that value, you are on the "bad side".
Well this simple question will get them thinking
>"Hey! Maybe I SHOULD be rewarded for my services?".
This I will eventually transform into
>"Why am I NOT being rewarded for my anti-racism?"
Which will over the course of years, will turn into
>"I should be rewarded, and I am not, so these people are using me."
Expand their minds. Let them see that they are being used, that there is NO reward for their services, and at the end of the day the people that love them at all, are their fellow Whites. Then they will become healthily, and unshamingly racist and ethnocentric towards their own people.
