Cassius thinks it's okay to destroy relics of other religions as a way of promoting your own, plus the whole "85% white" thing. It doesn't get much worse than that.
What have either of those things got to do with 'nationalism' in of themselves.
Nothing really, but that just goes to show you the depth of liberal thought on this subject (i.e. none at all).
I would vote ghost_white/mint and/or RosettaStoned because both of them actually subscribe to nationalism as a significant aspect of their overall ideology. One should be careful not to confuse patriotism with nationalism, as they are entirely different things with a lot of different factors at work. The poll seems to really be asking which poster is more of the flag-waving "my country right or wrong" patriot, rather than who is the most nationalist in an ideological sense.
