So it depends on your own personal opinion about which social grouping can be called a race (and be subject to "Racial Abuse") and which ones are fair game because you don't like them. Seems a bit strange to be honest as anyone could take your criteria and say that, in their opinion, Islam or (insert your chosen social group here) isn't a race and so cannot be racially abused. There is a body of opinion that says that some racial groups can't be racist because reasons. Islam is often considered to be a political ideology also. There's a difference between calling the political parties out for their policies and unthinking abuse just because you don't support them.
