I disagree with a lot of the first post, and most of it is because I think you've misinterpreted a lot:
Point One: I don't think the comments about the cars on eBay are meant as hostile; they are simply the opinions of some of the posters. That they are sometimes (or even often) negative doesn't mean they are hostile. In my experience, the comments tend to be right about the cars - they correct inaccuracies and point out previous errors in judgement made by the seller. Personally, I see no problem with informed opinions about the cars on eBay. Saying that such comments are hostile is on par with assuming that every inaccuracy in the ads is a malicious attempt to deceive the public - I don't think either case is true.
Point Two: I think the case is similar with the comments on ricers. I don't think any car fan is derisive when someone makes intelligent, well-reasoned decisions about performance enhancement, regardless of car marque. Most of the comments on rice-cars are about poor choices for performance enhancement (someone taking a $10k Honda and throwing $20k into the engine to get something that won't beat a $30k Porsche turbo on it's best day) and "all show, no go" add-ons to give the illusion of performance enhancement (silly, huge wings, a device that makes your car sound like a turbo, a roll-cage made of PVC pipe, performance stickers). I spent a healthy chunk of my time on this planet being young a broke, and I can offer you my assurance that you don't have to be dumb as part of the package, unless being broke is some sort of career choice.
Point Three: You say don't be like your dad. Why not? I mean, was the guy wrong? Because if the comments on this board can stop just one person from buying a 1969 911T and adding Turbo flares or a 993 kit while leaving the 2.0-liter engine untouched, that ain't a bad thing. And if that pressure pushes people out of their Hondas and into Porsches, thank goodness, because Greg, I don't want to grow old in a world with 40 or 50 year-old men try to solve their mid-life crises by souping up a Honda Civic.
So please, Dads - run out to the garage and tell your son his 1986 Civic doesn't need a turbo-wing, color-striped tires, or a 500-watt surround-sound stereo with flip-up DVD system. Rib the little fellow about the performance stickers for products he doesn't have installed, his multi-colored lens covers, and that frickin' under-the-car neon light show. Instead, convince him to sell that thing and help him restore an early Porsche car, soup-up a '68 Camaro, push a rusty Corvette into the garage and leave him with some tools and a MIG-welder. Tina Turner says we don't need another hero - we don't need another rice-boy, either.
