I think it's really important for activists and allies to recognize that sometimes it's okay to let this kind of shit go. Not because it's okay that it was said, at all. But because constantly confronting and educating people is not our job (at least not full-time, maybe part-time, heh). We need to protect our safety and our sanity if we're going to be effective at whatever our job actually IS, or even if we just want to go about our daily lives without having a goddamn breakdown.
