So, she sounds pretty butch here, but I wonder how long it will actually take, on planet reality, for her to cave.
A few hours?
I would take her more seriously if she simultaneously made a joke about Mohammad, or Islam, and then said "hey, you want an apology-well bite me".
It's not exactly brave to refuse to apologize to no-name losers on the internet and ditto for offending the precious and exquisite feelings of people who are offended on behalf of special interest groups such as Native Americans.
That's a pretty soft target for comedy. It's not "brave", it's very cautious and tepid stuff.
Anyway, this is sort of like deja vu all over again, as I was pretty impressed by Amy Schumer for a few hours, as well until she caved.
