It seems that those who have lived in or near Bournemouth are more likely to dislike them, two guys that I know who went to Bournemouth uni feel that way, the idiot fringe that wish to build a rivalry seemed to have achieved their mission with them; those friends that have had effectively nothing to do with the town though are pleased for them.
I'm in the later bracket. Truly delighted for them. I'm not falling into a bitter trap of building another toxic relationship as we have with the Skates, Bournemouth is the little brother.... I couldn't be happier at their success, it is of mutual benefit to have us both in the top flight.
