I'm aware that you asked Nicholas, but I couldn't resist the urge to respond (I'll say ahead of time that I don't know whether or not Nicholas agrees with my response. I only represent myself.).
Whether it's true or not, restating those points over and over in the form of unsolicited advice or criticism will not have the desired effect of convincing people. It just causes friction. Peter Goldsbury's post #66 hints that a wise man knows when to speak and when to remain silent.
If you think your neighbour is ugly, do you think that every time you see him, you should tell him that, and advise him to go see a plastic surgeon to fix it? Do you think that he will appreciate your honesty, even after he has told you over and over that he happens to like his looks and so does his wife?
Ofcourse it's a different matter if he asks your opinion about his looks. But even then, one might try to avoid hurting his feelings or insulting him by choosing ones words carefully.
You don't have to go to religion. Wars have been waged over other convictions.
Um, it's a public forum. So, there is no "unsolicited advice" nor "unsolicited criticism". It's public. Forums on the internet are specifically designed for this. So, should my neighbor rent a Public Meeting Hall, invite all people inside to "communicate" and then proceeds to talk about how ugly he is, then, yes, he is inviting other people to comment on that "conversation". That is Internet forums, not someone living next door and unceremoniously telling him/her that they are ugly. Apples and Oranges.
Also, with all due respect to Peter, but I find it ironic that here we are on a thread discussing how we should converse about not taking Morihei Ueshiba out of context yet we take a snippet of a translated work about Buddha to apply here. Could we also not point to the monk who carried the woman across the river? What, you're still holding on to that?
