In matters of the law “sympathy” is of very limited relevance.
The law is supposed to treat everyone equally.
That’s why the lady wears the blindfold as she holds the scales.
If we're going to start applauding this kind of thing to be consistent the standard should apply to ALL groups who self identify and associate by race.
That would include applauding a similar attack on a get together of your local MALDEF or NAACP chapter.
