From a practical standpoint, every argument with a seller has the tipping point when one has to decide whether to walk away and cut losses or sink more time and energy into something that is going nowhere. Rather than continue to waste time and argue, I decided it was easier to cut my losses, sell off the parts, and move on with life. I came out about even and chalked the rest up to experience with a bad seller. It was not a huge amount of money in the end. There are probably quite a few other people here who have done the same at some point or another. But that does not somehow turn them from victims into willing accomplices or enablers. Everyone has a point where they want to move on with life.
I guess it all comes down to choosing your battles. Same as above: As a society, I think too many people ( lazy parenting is a good example/ being a "friend" as opposed to a responsible leader, as is the lenient legal justice system) take the easy way ( or save energy) out and don't challenge spoiled, entitled, crooked, prima Donnas, narcassists, and sociopaths. If someone blocks my way with a gun or knife, it's apparent I'd better act, fight or flight.
If someone brings me a misrepresented item with the complete intent to screw me ( know in their hearts) and I know it then, or find out after, I'm pissed. Clearly they are playing me for a "Chump or a Sucker". I consciously and knowingly will not wear that handle or give a scum bag the satisfaction of duping me and moving on to hoop others. That's how I was brought up. Do unto others as you would have them do unto you. I don't dig getting "done" by anyone.
Am I going to get knifed or shot or my ass kicked to save my $$ and pride and morals, likely not, but that's moving to a whole new level. I will simply look "said seller" in the eye in a one on one in person, nod or point, or vocalize at the hidden or misrepresented trait, and say I've changed my mind based on new information. If discovered after/missed by me, or comes to light in a over the internet, phone, bad pictures, I will equally try to cancel the deal or get reimbursement to a misrepresented item. There is no argument. Agree to disagree if you want. The jig is up. Bully looses. ( the sale anyway)
We all can justify our actions or inactions based on our personalities. My way doesn't make me any better, stronger, or righteous than you or Shawn. I can't lie or misrepresent something because that's me. I bet neither of you can either. What we choose to accept is a personal choice and I respect that.
There was a guy on the Cabe that took advantage of me a couple years back in a series of bicycle sales and I called him on it and made his morals semi public. He was furious. I have no regrets. It came to light that he is that type of person ( duped others) and that's fine. At the end of the day, you have to live with yourself and I suppose he can. Bad Karma I say. Who needs it? Don't ask who he was. That ship has sailed. Integrity is a ( almost) lost trait. Right along with consience.
