It isn’t an attack on her character to say she will most likely join the previous voting block of 4, making it 5, to swing it in favor of DACA being repealed than it is to be offended when someone states water to be wet. If anything, it actually something both sides agree to be the inevitability.
Is it generalizing? Yes. Insulting? Not really. Not intentionally, I don’t think. And yes, people who think that could be wrong. We don’t know for sure how she will vote or even if one of the precious block may even defer. But that is also very unlikely.
I am mostly saying that it entirely depends on Texas. Not Barrett. As Texas has tried this kind of little stunt before in the 2020 election and the Supreme Court refused to even hear it. That also could happen again.
