You're sincere, but in order not to upset your views you avoid talking with people who think differently. You pick your thoughts from conversations with people like yourself, from books written by people like yourself. In physics they call it resonance. You start out with modest opinions, but they match and build each other up to a scale ...

... one person with their mind made up can shove a lot of folks aroun'!

So many men, so many opinions.

Do not interfere when your opinion is not sought.

It is difference of opinion that makes horse races.
