The justifiable counter argument to abuse is abuse is that is much easier to define it as such if you, your family and generations haven't suffered by people now saying that all abuse is the same.
It's also harder to accept if right before your eyes you see tangible evidence that all abuse isn't the same, that when it's directed at a certain demographic it is dealt with and responded to very differently then when it's towards your demographic.
It's like someone cheating, going 10-0 up and then saying let's start from now, we'll play by the same rules but we'll keep our 10 goal advantage.
Personally I don't care what's said towards me racially, however to class it all as one without context towards history and what certain groups have suffered, and continue to suffer is a bit narrow sighted. Especially when that abuse has and continues to have the threat and actual violence attracted to it.
