Put yourself in the Taoists' position.
1. You know nothing about one of your own, who has always been trustworthy and virtuous for decades up to now, having raped a woman. You couldn't have known. Why would you have suspected? Who would have told you?
2. Said woman belongs to a sect known to have a list of unreasonable grievances against your sect, and has in the past slandered your sect founder for any number of supposed slights.
3. Said woman comes accusing said member of your sect of rape, which happens to be true, but for which she supplies no evidence other than her word.
4. Said woman comes armed with swords and is making threats and behaving belligerently on your home territory.
5. At the same time she's there, there's also a group of Mongolian warriors there also looking for trouble.
Without the benefit of omniscient readerview, what would YOU think?
It's so easy to Monday morning quarterback this, but what if you were actually one of the Taoists there? Would you actually give this threatening woman time to explain herself? She has swords drawn on your people at your home! If she's got a legitimate grievance to air, she'd better put down the weapons first.
