oldest fringe kook retort of all, 'everybody does it' so STFU
that's like a bank robber telling the cops lots of people rob banks, what's the big deal?
People like Flash desperately want others to think of them as thoughtful, fair, non-partisan people. But because people like Flash are incredibly lazy, they think that getting others to think highly of them requires casting themselves as above it all who can see the scorn in all sides. That way, Flash can present himself as some kind of thoughtful, fair, even-keeled person instead of the lazy person he really is.
It's easy for Flash to throw up his hands and say it's all bad because doing the work of recognizing distinctions and differences might result in him having to come down off that pedestal he put himself on.
He's just not prepared to do that because he's scared and lazy.
