Being a centrist doesn't mean that you have to compromise on everything or you are a conservative in disguise. In fact, I consider myself a centrist and I have very strong lines I won't cross.
In my case it means that you are not torn into extremes, and that you prefer a way that respects most people rights without sacrificing basic rights or certain ethic values.
And the image there is quite low effort. It's trying to convey a message that either you are pro civil rights, or you want to kill black people. I don't think there's even a middle ground there, or a fair comparison.
