I'll break out an old interview between a pro and anti back in the early days.

Pro: What’s your message to Anti-GamerGate?
Talk to me. Talk to us. Keep an open mind. I’m not what you think I am. None of us are. You don’t have to agree with us, but you also don’t have to make assumptions about us. We really aren’t as different as you think.
(Self explanatory. Talk to us in good faith)
Anti: What’s your message to GamerGate?
To those only ever truly interested in discussing games media ethics and can bring themselves to acknowledge and denounce the evil to have come out of Gamergate: Please see the truth for what it is, that games journalists can err without being villainous, and that there is no attempt to persecute you, and come, join in the continuing discussion without needing to bend it to your will.
(Abandon your cause and "accept" that nobody is prosecuting you, accept the way WE view things as the unquestionable truth)
You try to have civil and compassionate dialogue with someone who thinks like the Anti does. To them, that means their way or the highway, you 100% accept their opinion as fact and denounce all others.
