She did not need to mention those groups at all. This is across the board blame.
‘She did not need to mention those groups at all.’
but she did need to mention white racists, though...
It is not she specified only 2 groups. No one could take that to mean across the board unless they read something there that isn't! She could have left it as racism if she meant across the board or have listed all groups by saying simply " racism by all". I guess Antifa's threat to Trump supporters did not register.
