If you are ever asked this question, or any variation of it, by someone who supports Israel, do not dignify it with an answer.
It is nothing but an attempt to distract from the obvious fact that for the best part of a century the Palestinian people have been living under the boot of an oppressive apartheid regime that is guilty of crimes that far exceed anything Hamas could ever even dream of committing.
Wow, that was beautiful. Personally I still prefer "No, I endorse them. The oppressed should fight back against their oppressors." But on TV where everybody's wearing a suit and he's expected to represent his people and their struggle and will be judged on dumb liberal 'civility' bullshit, he handled it perfectly.
