The process I described in 1st example is that of a stock investor. Are you saying all stock investors and brokers are crooks?The only difference between the two in this scenario is that one guy made less of a profit than the other. What if fair market value a couple of weeks or months down the line is $3k, and the second guy sells for way more than the first? Is the second guy now the scumbag, and the first guy is the fair one? Flipping, scalping, it’s all the same thing. I don’t care either way, to be clear. I overpay for stuff all the time with zero complaint. If you’re embarrassed when people call you out, grow a thicker skin.
I once read that it takes less energy to speak (or in this case, type) 1000 words than it takes to warm a cup of coffee. I take it to mean words have very little power, and I tend to agree. We’re all grown men (and women) here, ignore the ribbing and take it as part of the game. Or, you could block anyone who messes with your sales post. Everyone wins.
As well blocking people is a form of cowardness. I would rather make them think twice about coming up on my thread with disrespect.
