I'm from the north of England and even there I can count on one finger the number of times I've heard anyone even mention Scotland other than as a nice place for a holiday. It's not a case of hating, or even disliking, the English really don't hold any grudges/dislike or anything of that sort that I can see. That's the sole reserve of the Scots, and they (collectively, not individually) seem to assume we're all still "against" them (from what I can tell, living in Scotland now). They regularly, if in humour mostly, refer to hating the English and the English hating them, the truth is its very one-way.
Any perceived anti-Scot behaviour is most likely to be solely down to the fact that most people forget they exist, much the same way that most from Liverpool forget that Manchester exists until someone brings up some childish sporting rivalry or the fact that someone got a supercasino and someone else didn't etc etc.
As awhiles says, for the most part the English (possibly more the northern english) are baffled by why you hate us. When I asked about this I got political waffle and anchient history lessons, neither of which are changeable on a single-person scale and none of which are representitive of current English thinking IMO.
