This should definitely be the standard. My spine is all sorts of fucked - because of a car accident, not even my choice. Every single insurance company refused to cover me unless I paid more than all of my other expenses combined and even then I wouldn't get any coverage for skeletal, neurological, or pain related issues. I hired an insurance broker and still she couldn't swing me anything reasonable. So - being obese, a choice, is not okay to discriminate against. But conditions a person did not inflict upon themselves are allowed to be discriminated against. The logic here in the states gives me migraines... and fucks my life over.
