If It's Not Scottish, It's Crap!

OK, one more thought on the British election. I understand the need for a Scottish Nationalist Party, since it provides a voice in Parliament for people who want Scotland to be an independent country (not a terrible idea, in my view). But, seriously, do the Scots need their own Socialist and Green parties, too? Are Scots really this proud and disagreeable? With a rational people, those who wanted independence would put aside their other policy differences until independence was achieved (cf: Ireland, America). Or, realizing that independence was not going to happen, they'd throw in their hats with whatever major Britain-wide party they were most sipatico with. But we're not exactly talking about a rational people here. We're talking Scots.
