I have a big problem with people who try and distort a person's sense of reality.. Or 'gas lighting'. I guess after a certain point, the victim starts doubting themselves and need reassurance that what they're sensing as real, is. For example. I look at a black mug, and my friend tells me it's white. As how white is defined and represents in the English language. I am incessant with it. Particularly in situations where the issues are quite serious. I know that there have been many stand-up comedians who make fun of feminine styles of debate, and urge men to just say "I'm sorry, I'm wrong - you were right!" and just walk away from it. I believe I have walked away from many arguments with me where I knew deep inside, the 'mug was black.' 90% of the time it's not an issue worth pondering, probably.. But, at which point to you become 'incessant'..? When it becomes a 'legal' issue? When your reputation is at steak? Examples?
