I always wonder how people can respond to a question such as:
"Drilled rotors result in possible rotor damage"
Answer: I've never seen a rotor fall apart due to drilling.
Implication: I've never personally observed or experienced the situation, thus it doesn't exist.
However, we don't know how many drilled rotors this person has observed. It could be thousands more than the average person experiences in a lifetime, in which case this person has some life experience to share and learn from. Invariably, it's a person just like you and me, with limited experience with different usage on different cars and operating under different circumstances..... a limited sampling from which to base a valid conclusion. But what the hell; if I didn't happen to see it, it doesn't happen.
Another observation is when people cite facts based on what they've read somewhere on the Internet or they use pseudo science; B follows A, thus A causes B. Popular theories (the world is flat, drilled/undrilled rotor are fine) perpetuate because they're popular. Like books, one should be skeptical about anything you read. Just because it's been written (and even typeset) doesn't necessarily mean it's true. Consider the source if you can.
Perhaps my response is too serious for this thread.
