I think you mean they are calling Chazal “Bigoted” as a slur, and “we know better”?
I don’t like the way you phrased it, but the T”T might explain himself somewhere along those lines.
We both know that the Torah does not believe in “equality”; we were in agreement in a discussion regarding hilchos tzeddakah. The Torah affords different status to Kohanim. Need I bring more examples? I wouldn’t use the word bigoted for any of those either.
I get my morality and values from chazal. I don’t tell chazal what their morality and values should have been.
Having said that, the T”T’s pshat is not mainstream at all, as has been noted.
