It's important that when people who are ostensibly "on our side" start behaving in ways that are hateful and damaging, we are willing to speak out against them, rather than appear to collude with them.

I think of the way that in the election campaign John McCain had the guts to disagree in public with that lady who started shouting about Obama being an Arab (implying terrorist), and tell her "No Ma'am, he is a decent family man citizen that I happen to have disagreements with about fundamental issues". That kind of response needs to be more evident than it appears to be. When honorable people fail to step up to the line, they stoke up an atmosphere of hate, and this can be terribly dangerous.
