All I'm trying to point out is that just because a group of Youkai killed a human at the epoch of Gensokyo, whom was doing violent things to begin with, doesn't mean modern-era Gensokyo is grim.
But to answer your other questions:
>Mizuchi trying to get humans to fight tyrannical maneaters is bad? Being mindless, powerless fearcattle is good?
No, but she chose to rashly fight on her own and was outplayed, caught out, and killed. By Suika's description, Mizuchi was one of the few humans who was capable of playing the long game, lucky for her, one of the better outcomes occurred since the Village has a very high quality of life and Youkai were reverse-domesticated.

But whether or not they're 'powerless' is an open question for me. They are more ignorant then the average Youkai on a whole, and the average Youkai probably knows much less then someone like Mamizou or Aya, so they can't really advocate for themselves. However, Marisa is proof that a determined human can learn magic from a young age and explore relatively safely and there's like four or five other ways to become strong enough to do danmaku that doesn't involve going Youkai.
Such humans aren't going to get whacked because that's not what the Youkai are worried about, like Mizuchi correctly identified, they don't want humans to organize because if you can get enough humans together you can do just about anything you want.
