Holding my tongue

I find it it really hard to hold my tongue on a particular forum. I really have to try my darndest to leave things alone. What I have learnt though is people really see things in a different light. I always think to myself, nobody could see something differently to me. Everyone must see the same line of thought as me, but it's just not the case.

What I see as clearly being right, other people see as wrong. I get such a shock when people react in a different way to my way of thinking. I look at myself and say, am I crazy, am I blind, what aren't I seeing that someone else is seeing, can't they see it as clear as daylight?

But I guess the answer is, we all are quite different and yes are brains react quite differently too. So that begs the question, is there ever a right answer? If not that's pretty scary!
