I don't think anyone is denying that race was ignored in this case and people were afraid to talk about it.
But - do you see the issue with using a label like that? Most Pakistani men are not abusers - as you said. To say Pakistani abusers - it applies in some people's mind an assumption that Pakistani men are abusers.
It applies to any other group - put the group "type" in front of a horrible word and it creates an association - just like Muslim terrorists etc.
If you don't belong to a group that gets labelled in such ways, you might not be able to appreciate what that means.
