If you don't know the rules, you shouldn't be flying until you do know
Whilst I agree pilots should know the rules, IMHO this was a bit harsh, most pilots on this forum are not full time professionals and as such are often not as up speed with the rules and regs as maybe they should be, I would much rather someone who is in this position feel that he can ask rather than being driven away by responses such as this and remaining in ignorance.
