> should not be obligated to adapt to a crazy person who is only willing to

Actually yes it should and that's why we have non-discriminatory laws (the subject of the article) in the first place. In civilised countries we do that in order to avoid what John Stuart-Mill called the tyranny of the majority. But since you already see these minorities as "crazy" I hold out scant hope for your love of other people. I even think the US even has some constitutional basis for the Protection of Minority Rights.
