A: That isn't what you said. You said: "Take the case of MySQL injection."
Second, bringing up MySQL when talking about SQL injection is rather odd, and I don't see any reason you added that except that you don't realize MySQL is irrelevant.

Your "arguments" were very poor. There was no need to detail them.
What? Where did I say so?
I said "people does not hand wave SQL injection vulnerabilities by saying they haven't encountered it in their 10 years of experience with MySQL".
That does not mean all sql injection vulnerabilities are limited to MySQL!
Is this one of those of tactics that are frequently employed by php apologists to derail arguments against the language?
