I would think questioning supporter’s motives for a cause that you directly benefit from, is not the best use of your time nor does it serve the cause in general in any positive way.

If you were building a house and your neighbor offered to help, would you question their motives? How would that help you if you did?

Instead of alienating the very people who at the very least are bringing more exposure and knowledge to the plight of African Americans, perhaps you could be grateful that others are helping to build your house and that the foundation is stronger when people who have different experiences bring their willingness to help to the cause.

While white people learn to be better humanists in general, perhaps you might learn how to better respect allies who help advance your cause by redirecting your judgement of other’s motives to those that are actually working against you. If you want real change, take all the support you can get and build a coalition. Accept help where you can get it,, and be grateful when someone helps you. That is how we can all benefit and become stronger together.
