I voted other.
Kinda can't believe I'm the only one so far to do so.
My first thought was "yes, okay" but then took the question to be mostly about rationale of 'okay to protest him who is unsure of what is sexual assault.' And given the linked piece, sorry I ain't seeing that. It's just rehashing debate I feel we've already had and thus far haven't seen anyone convince me that what Trump said is sexual assault, nor if what he said played out, it would be sexual assault.
In a sense, okay to protest it, but in another sense it is protesting based (seemingly based, I'd say) on misinformation. Or akin to "okay to protest Elizabeth Warren who doesn't understand 5 times 4 is 20?" I'm serious, that's how nonsensical it appears to me, which is why I voted "other."
