Zeuhl raises an interesting point. What is racism? According to the CPS:
"A racial group means a group of persons defined by reference to race, colour, nationality (including citizenship) or ethnic or national origins. The definition is wide and victims may come within the definition under more than one of the references. Gypsies and some travellers, refugees or asylum seekers or others from less visible minorities would be included within this definition. There has been a legal ruling that Jews and Sikhs are included in the definition of a racial group [Mandla v. Dowell-Lee [1983] 2 AC 548].
A religious group means a group of persons defined by reference to religious belief or lack of religious belief. This includes Muslims, Hindus and Christians, and different sects within a religion. It also includes people who do not hold any religious beliefs at all."
If you still feel it is a racist incident not covered by the above:
"A racist incident is any incident which is perceived to be racist by the victim or any other person".

If you cannot invoke racism almost the same laws apply to religious incidents.
