"Debate Me!" Screamed the Troll

The Internet troll's demand that you "debate" them is a demand that you submit to trial at a moment of their choosing in a court where they are judge, jury and executioner as well as prosecutor; with only yourself for an advocate, no time or opportunity to prepare your case, and on Twitter, a 140 character limit to each and every statement for the defense.

Some debate, that.

Remember, friends--no one is obliged to stop everything they're doing and defend their opinions to an anonymous stranger at any and all times. This is all the more the case if the person called on to defend their opinions is a private individual unaccountable to the public, and absolutely the case when the person making the request shows every sign of doing so in bad faith.
