I never said it should be taken seriously or not taken seriously. I just meant that you can't assume either way--it is up to the reader.
As far as I understand it, that whole site is pretty tongue-in-cheek.
In the quote you posted you have your own answer. 'In many cases...' vs. every case.
For example, maybe your dad was really into Campy and he told you as a kid (as my dad did once) that Campagnolo makes the best components money can buy. Now when I see the Campy logo I think of my dad. I don't own anything Campy these days since I am a poor student and there are better values to be made
Lastly, it's hard to say who races and who does not race. I don't know enough about them in particular to decide that, and I don't really find it relevant anyway.
Actually, you're right. I don't race either, better sell my bike and get a thruster fixie.
