And I think the difference is in numbers. The number of "bad apples" in mainstream Scottish nationalism is actually very few. There is very little "English Hating" outside a few internet trolls. The SNP is not anti-English, none of the SNP supporters I speak to regularly are anti-English. My English friends tell me they've never really experienced any anti-English abuse.
Which is why the French, Irish, Germans and any other EU students can get free tuition in Scotland but the English are specifically excluded? Also, I've heard many stories from my friends about some rather disgusting abuse thrown at them for being English, that's not a very good argument about how many bad apples exist.
Compare that with English Nationalist parties, like the EDL, the BNP, Britain First, and to a much lesser extent, some parts of UKIP. They are exclusionary, they are about ethnic nationalism, "English Jobs for English People", "OUR country", &c &c. Outside scare stories by the Telegraph, you don't really get that in Scottish Nationalism.
The simplest form of English nationalism is the idea that it's fundamentally unfair that Scottish people can vote on Scottish and UK matters, Welsh people can vote on Welsh and UK matters but the English can only vote on UK matters. I think England should have it's own devolution, England as a whole and not some artificial "regions" which are an exercise in Labour gerrymandering. I think the English people have a right to an undivided nation just as the Welsh and Scottish do but by expressing these views I get associated with racist scumbags when if I was a Scot saying exactly the same words about Scotland I'd get upvoted to the top. How is this fair?
Of course, one could argue (and I have done so) that Labour and the Tories are Nationalist parties in their own right, but I don't thinkt that's what we're talking about.
The Conservative and Unionist party is nationalist now?
It's extremely bigoted to say it's morally acceptable for some nations to express nationalism but not others and yet I hear this all the time from Scottish nationalists, this idea that their nationalism is somehow more justified when really Scotland gets a far better deal than England constitutionally in terms of devolution.
