Yes, it does. Patriotism is (in addition to what you say about traditions and culture) devotion/good feeling/pride to one's country: ie an arbitrarily drawn border.
I think you're simply cherry picking parts of what patriotism is. Even in the narrow sense, it involves a devotion to one's country, and therefore is idiotic by nature because it does involve giving up some rationale and independent thought to the pack mentality.
Haha....are you ignoring that people justify their patriotism?...and that patriotism isn't a blind devotion to ones country....you need not give up any rationale in pursuit of being a patriot....you can be a patriot simply by upholding and defending those rights that you feel your nationalities values, traditions and shared history engender in you as an individual.....it is not idiotic to identify and be proud of that connection, or to defend it....or to oppose those who seek to abuse those values and the sense of identity for their own ends....
Don't believe the BNP, EDL and groups like them....they are not patriots and they have no understanding of our shared values and as such attempt to change the definition and meanong of such words as patriotism and national pride....
Feeling proud of the place in which you were born or the values to which that country aspires is not idiotic.....quite the contrary.
