I agree Haseeb's comment was sexist, and I'm glad that Keegan called him out on it. But I think the punishment she's asking for is too strong. She seems to be implying that he shouldn't be allowed to have a successful career after making that comment, which I think is a massively disproportionate punishment. Also, this isn't "tacit acceptance of entrenched sexism". There was nothing "tacit" about her calling him out, and her response and Ruggeri's response were not "acceptance". In fact, if every sexist comment got called out like this, people would stop making sexist comments. The problem is when people make sexist comments and don't get called out on it, or when the incident is brought to higher authorities and the authorities defend the sexist comments--neither of which happened in this case.
