"There's no difference between anti-shortness and anti-Blackness, except the intensity and commonality" is certainly a statement, its I guess correct in the tautological sense that "X and Y are not different if you exclude all the differences between them", but it's also not a useful statement at that point.

I'd ask in what way the point you're trying to make is useful, either analytically or rhetorically. I don't see how it is offhand.
