You are correct in your "understatement" claim, though I suspect unintentionally so. Yes, "avoiding politics" cuts into time you could be spending advancing progressive politics. So does writing software. So does watching a movie with your spouse. So does sleeping. So does every single thing that isn't literally "advancing progressive politics."
"No politics = politics" is an utterly vacuous statement.
