Well, after reading most of the 12 pages of nonsense, I can see that Porsche snobbery is alive and well.
Funny thing is, most of the folks coming up with their "who not to wave to" lists are the ones that claim those who own non-air-cooled 911's are immature and childish. Pot, meet kettle.
People who advocate this type of stupidity, whether in jest or not, give Porsche owners a bad reputation. Too bad there isn't a test to ensure that a Porsche owner is simply a Porsche enthusiast prior to said owner purchasing a Porsche.
Here's a graduitous shot of my WATER COOLED, FRONT ENGINED 944S2 to pollute the waters here:

I never passed a 911 I didn't like. I believe all three cars that are
behind me are of the air-cooled variety.
