..."Imagine if (fill in the blank) happened to/was said by/was done by a Republican." (Or in this case, maybe what we need to imagine is: what would happen if the endemic racism in this country was targeted against whites, but the same rules apply.)
Just imagine, if you will, the shitstorm that would ensue if the newly-elected President whose election triggered this behavior was, say, an old, white Republican. Imagine if blacks across the country, responding to the election of said white Republican, erupted in an insane spasm of hateful, racist acts targeted against white people.
How long would it take for the blacks in question to wind up in prison?
How many of these crackers will end up in jail?
Yeah, that's what I thought.
