I personally think it is weak to take pride in one's nation or race, since what one's nation/race has done is not what oneself has done, thus one has no reason to take pride or feel shame over it.
For this same reason I think it is just as alright to shout racial slurs as it is to make 'normal' insults at people, aswell as degrading someone's nation. They should not feel any pride or shame over it in the first place, since they have no reason to do so, for the reason I mentioned above.
