I think that #5 is a bad point, as there are multiple reasons why someone might get irritated with a trait of another person, and "I see that trait in myself" is only one of them. I don't think that it's even a "probably"; it's at most a "perhaps".

#7 is way more complicated than it looks like, as it only works under the assumption that humans are morally consistent (we aren't).

Other points look fairly sensible IMO.
