Let us propose a hypothetical - some leftie comes at you with a "minority" support argument. Ive been playing with this, and found the dark heart at its core. It all boils down to the idea of the minority. Heres 5 bullets that i think will help kill it in all but the most brainwashed. It certainly will hit them with a dose of cognitive dissonance.

1. The deepest, and one of the most diverse minority groups in the world is the super rich. They exist among all races, are usually numbering less than 100 wherever they are, and have the most to lose in life from the majority.
2. This "minority" is the one you are most deeply against as a leftie (and we here hate most of them for being cabalites too, but that's a tangent), and yet it always seems to benefit the most from your efforts to help what you think are minorities.
3. This specific minority you claim is "the white man", thus ignoring the plight of poor white men and women all over the world, and presuming there are no wealthy black, arab, asian, or other non-white individuals. So racist, isn't it, to presume wealth based on skin tone.
4. As this minority has the smallest size of all groups, but the greatest influence in how the world works, surely this negates the idea that "minorities have no influence" ?
5. Most of this minority is probably footing the bill for your side's activism, and we can prove it with receipts. They certainly are the biggest beneficiary.

If they try to redirect it, just focus on the minority point, and keep them from claiming its only a PoC issue.
