As ive gotten older i realise most of the things we persecute others over we have done ourselves at some point in time.

In some cases it is hypocrisy...in others though it is that because we have been guilty of it we are aware of its dangers and consequences (because we've seen or experienced those too). We know the ignorance, the stupidity, and the wrongness of it. I don't think pointing that out to someone is actually judging them for it. And when they ignore our warnings and criticisms we tend to call them fools and I don't see that as judging either. Hypocrisy only comes into play when we are pointing it out to divert attention to them and away from the fact that we are doing it or have done it. Otherwise it is to each his (or her) own, and they'll just have to find out for themselves...I may not like or agree with it but it's none of my business.
