Is UK riddled with racism?

Yes but no more so than in the united states if I'm honest I believe there is more racism in the united states. The racism in the UK is done by petty people who have nothing better to do. The fact that the UK has become so multicultural means that the UK has become a melting pot in which tolerance and acceptance is mandantory so although some people may be racist it is not expressed as much due to an oppressive fear saying the slightest thing that may offend the minority while the majority seem to have a right to be offended.
