Alas, you have fallen victim to the phenomena of "For-Sale-Police-Syndrome" (FSPS) on this forum (it exists on many on-line forums as well). Let me say that I consider my fellow SOCers as friends, but sometimes the urge to Correct, Assume, Distrust and Ridicule is just too overwhelming to resist. Once the backlash gains momentum, then you become the bull in the ring.
Additionally, membership or frequent posting on this forum would not necessarily shield you from FSPS.
Personally, as a paying member, I find this forum the best bang-for-the-buck in entertainment value. The caveat is to take the commentary on here with a grain-of-salt and enjoy the show.
As with any other social media I partake in, if a particular thread interests me, I read on. If not, I simply scroll past and move on to another post. Life is too short!
BTW, good luck with the sale of your windshield.
