See, this is the problem. The difference between calling someone Scottish, Ginger, Lanky, etc, and calling them a gypsy, is that you are not going to have someone seriously claiming that "Anyone who believes gingers are in the main honest law abiding tax payers is living in cloud cuckoo land."
I'd love it was true that basically everyone got on with everyone, and so we could have chants about gypsies, pakistanis, etc and it WAS just the same as chanting about fatties, or gingers. But it isn't. Because there are clearly a lot of people on here that DO have a real problem with some of these groups. And, as a self styled member of the PC brigade, then the reason that these chants get to me is that, when the chanters may claim that they are just having a bit of fun, and that it's all good banter, really they have views like Triplej.
And if you do have views like this, then I honestly have no idea whether you are right or wrong - I don't have any stats on tax payments from different communities. But if you really do hate any section of society, I'm not sure that chanting about it at a football match is the best way to vent these feelings.
