I've not heard any racist abuse at football since we were at the Dell - and let's face it, in most grounds these days the fellow supporters around anyone giving that stuff out would turn on them very quickly. If anyone makes a noise during a minute's silence the group around that person jump on it straight away...unless it's a cough etc.
I find it hard to believe that in the Premier League these days (and this is going by what i hear) these guys get subjected to a huge amount of racist abuse pitchside. I may be wrong, but i haven't heard it for years. I think that homophobia in the game is a much bigger issue, given that players won't come out as being gay.
As for Rose, take a stand if you feel like that and quit.
