You are spouting utter rubbish. The vast majority of people are decent and honest. They have no wish to be deceptive and just treat other people in the correct way.
No, I think the rubbish is yours. I would suggest that almost everybody lies from time to time, and for a multiplicity of reasons. It may be to save themselves embarrassment, or to protect someone else from unpleasantness, and can be for altruistic reasons.
But in the context of this forum, I suspect it’s universal be it punter or SP – including yourself, Winker, unless, of course, you never have to cover your tracks to family or friends or colleagues.
