You don't have to be a fan of Matador and your favorite meal doesn't have to be frikadeller and persillesovs. In the summer you are not forced to eat strawbarries with cream and celebrating christmas is not even a requirement.
It is your choice to be a vegatarian or live of kebab, you can dress as you want; wear a burka or a shirt skirt. As long as you let the other people be, who they are, you have every right to be yourself. As long as you tolerate the ones who disgust you and accept that others may have nasty thoughts about you, you can be who you are.
As long as you do not harm any one or break the law, it is your choice how to be danish.
