Not for you
Being a doctor is not a career choice that just about anyone can follow. Some people can not handle the sight of blood or having to cut someone open and fix a problem. We know that most of us here are not cut out to be a doctor for those specific reasons.
But there are some other ones that make someone unqualified, for example not treating someone based on their sexual orientation. As a doctor, it is your obligation to help anyone, no matter what race, religion, or sex. If you can’t agree to that, then you should find a different career path to follow.
