Two points:

Let's look at the muslim cemetery issue from a different perspective.  Firstly, it is not racial discrimination -- it is religious discrimination.  But who is being discriminatory here????   If a group of people want to be buried only amongst other people of their own religion, are they not the ones who are being discriminatory?

...which leads to the 2nd point.  Why is it that when a majority rejects a minority, it is called discrimination, but when a minority rejects the majority, it is not called discrimination?  When an ethnic group builds a condo. tower to house members of their group, or a retirement home caters to a particular group, or government establishes a drop-in centre for a particular group, why is this discrimination not condemned?
