Did you want her to genuflect as well? In spite of her being aware that she was being baited she still gave a very good and truthful answer, just not the one Stefanik wanted.
Asking if calling for the genocide of the Jewish people is wrong is an easy answer, it is. Asking if "calling for the genocide of the Jewish people" violates Havard's policy on harassment and bullying, Gay correctly replied that "it can be" not the blanket "yes" that Stefanik was trying to bully her into declaring. This after offering a hypothetical with no information (because it's a hypothetical) of who was doing the calling, who was the audience, and what were the circumstances - was someone on a soap box in the quad with a magaphone, was a student watching a video on their phone in which protestors were chanting "from the river to the sea Palestine will be free", was someone discussing their opinions on a telephone call and could be overheard, there are a ton of circumstances that wouldn't "automatically" rise to the level of harassment/bullying.
I know you won't like my answer anymore than you accepted Ms. Gay's answer however if you think about it, when cases make it to the U.S. Supreme Court, SCOTUS doesn't just issue a ruling stating "Yes it's Constitutional" or "No it's not Constitutional", they explain the case, other cases that are similar and which have established precedence, what law/case law they're depending up to support their rulings, etc.
Quit being so thin-skinned and seeing antisemites under every bush.
Asking if a verbal declaration made is a violation of a school's rules/policy against harassment and bullying really does "depend" upon ALL of the factors surrounding the statement made. That is entirely different than asking if making such a statement as an affirmative is wrong.
