Is the term blacklisted racist?

That’s part of it - and we should.
At the same time, as we see with ‘black’ ‘negro’ ‘African American ‘ et al - as long as one group wields disproportionate power, all attempts to have language by itself redress that power imbalance is ultimately doomed

Redistribute the power and the language won’t be as fraught
Not that it really matters, but wouldn't "disproportionate opportunity" be a more positive message? Otherwise it comes off like what you're seeking is power rather than equality.
