These paid doctors have trained and worked all their lives (and work bloody long hours too) to be able to help you with your health problems. They have to put up with constant abuse from patients, spend more time with other people's families than their own, they're constantly fighting against being overworked, they're underpaid, and they deal with underfunded working conditions 100% of the time.

I don't wish to be harsh but, if you don't respect others, they're not going to respect you.
