This notion that it is a one way street? That is a flat out lie.
The totality of a population in an entire society says little of the regional, local, or interpersonal and individual interactions between two people.
Just because whites are a majority in the nation, does not mean a white person going into Birmingham, ordering a meal and being told to !@#$ off isn't possible. It most certainly is, likely does happen, and would absolutely be racism.
If one is consumed with balancing the scales, they would need to commit a great many acts of evil upon their fellow human beings. In no way in hell does that give you permission to dismiss each of those many steps along the way as "getting even" or "not enough". Such crimes should be universally forbidden against ALL people, of all races and colors. That is how equality is borne. Of equal treatment.

Don't you go down that road of telling us "but they deserved it" for being X. Enough hatred has risen on the issue of race. Do not dismiss or divert from it when it occurs. Confront it, all of it. Do not give rise to any lest you find yourself contributing towards it.
