Personally, I find that as levels of 'cute' go up, so do the levels of annoyance... the fact that they're so helpless and can be quite stupid doesn't really do them any favours.
It's kinda like babies. Don't get me wrong, I'm not advocating punching the nearest baby in the face. They can be "cute". But then you get those weird times when you think you're the only sane person in the room when the kid in the movie theater won't shut the hell up, and the baby's parents seem to think that kind of shit is adorable.
Or if a kid throws up on you. Suddenly you're the bad guy for just being annoyed.
Well think like this Hourai, Babies do that "from time to time", koyukkuris like kiri's, if they aren't the "acceptable" ones, then they do what you mentioned 24/7 nonstop, which is even worse than babies.
Maybe it's peeing and crying because it's being abused? Most people (regardless of age) tend to act badly when they are taken away from their families for a life of torture.
"you're abusing Reimu?" Yes... oh, yes. "it's because she is so cute?" No... ooooh...no. "we just wanna be easy, can't you understand that?" Yes, I can. I simply don't care.
And now, the 1 million $ question: "Why won't you let us take it easy?" A why not? B *SMASH!* muhuhuhuargh... C because (insert a lot of moral justifications here - valid or not) D you killed my brother
Remember that you cannot call at home anymore. You can ask it to the public, however.
Or you can always say, "you don't let me take it easy, so i'm returning the favor", technically that may be true depending of you and what the yukkuri was doing.
