There's certainly an element of Scotophobia in some of the UK media and in British popular culture, however, this is the case with many other identities too (Ireland, France, Germany, etc.) and usually to a greater extent. The Scots also have a bad track record of sectarianism against Ireland and rarely raise a peep when it comes to some idiot tabloid or comedian slagging off another country that isn't us. British culture is pretty chauvinistic as a hangover from imperialism and sometimes Scots suffer collateral damage from that, but it's complicated since we're implicated in it too.
I find English people brilliant on the whole, though, not that it's proper evidence. They can be a bit patronising about aspects of Scotland but I've experienced the same from French, Americans, and Germans too. It's a big country thing.
