I don't know what it is, but I can't stand South Manchester, purely because of the student population and how some people deem themselves better for coming from the South compared to the North. Its probably gone on for ages. An arguement I used to put too though was, 'well where in the City are 90% of the deaths by shootings?', that generally, as a rule, shut them up for 5 minutes. That was usually in retort to them saying North Manchester is rough, which admittedly parts of it are, but rarely do you hear of shootings in N.Manchester, compared to South at least. Yes there will be arguements that other crimes are more common in the North, and that maybe the case. As I say, its probably gone on for ages but my general opinion is I won't go to South Manchester unless its absolutely necessary.
