I am not self aware obviously!
Seriously, society in the UK has a long way to go. But then so does every society. But at some point the best measures are not laws and faux levels of outrage but rather simply making them feel as foolish as they are. Out of 60,000 people there will always be the handful who let their emotions get the better of them or are indeed racists. Spurs turned the Yido BS into a positive. Gays claimed the 'queer' insult as a badge of honor. Perhaps racial name calling needs to be treated the same way? If an idiot/bully gets the response he wants then he keeps on with what works. Laugh at them. Find them, single them out and laugh at them. Everyone seated around them should point and laugh.
