I wouldn't take that as a rude comment, but a legitimate question and concern from an experienced keeper.
He's trying to help you and your snake. Try to think of it this way...when you're sick, do you want somebody trying to force you to eat? Or do you want somebody invading your private personal space? Or would you rather be left alone to rest and allow medication and time to take it's course?
Granted snakes and people are entirely different, some general principles can be applied to both.
This forum is an invaluable resource for keepers new and experienced alike. The common theme: we're here for the passion we share for these amazing animals. Find the keepers who know their stuff and soak up all the info you can. I had years of keeping snakes under my belt before finding this forum and still learn new things all the time.
Remember: we're here offering our time, knowledge and experience. We don't HAVE to offer our time, we WANT to.
