No one would answer that. It's a bullcrap question. "How are you different than a pos murderer?"
Are you answering a question like that? Of course not.
A, that wasn't the question, but B, even if you think its a nonsensical question - that would be your answer. I thought about this for all of two second before throwing out a, "I think that is an unfortunate and disgusting question sir, to compare my beliefs to that of a murderer just for the sake of your own publicity. I condemn his actions and any claims that my beliefs would lead him to those actions and I feel for all of the victims. God bless."
But his reaction? Get security, get him out of here, you need to go.
It is a public forum. The public has asked bad, dumb and partisan questions since they've been allowed to, all the way back to Rome.
Chicken shits like Steve King love to espouse their extreme positions on issues, because they don't have to face the actual public that they represent.
