I think back to OPs question - one can rightly argue for each of the four schools.
I don’t think W&Ls name impacts the student’s education nor law school prospects nor has it hindered UVA grads, nor W&Ms or Georgetown and all four have a slave history. Heck, UVA was founded by a slave owner.
Guess what - all four have a “history”.
W&L specifically addressed the name and is taking many positive steps to “enhance” the overall university history and is removing the name “lee” in other places.
@Yonkers6thBoro while i disagree with your assertion about W&L - I mean, I’m a Jewish guy working for a German company - they didn’t change the name but I’ve come to accept what the company (and country) stands for even today - but you are certainly entitled to your opinion but I don’t see any relevance to the topic OP asked for. W&L alumns are excelling through all facets of society.
