I think if they try and appease a liberal agenda they're going to lose their thunder.
They also focused too much on Cameron at the start of this season. Could be because he won them an award and they think he's the horse they need to hitch their wagon to, but Modern Family is hilarious because the whole of the characters is much more than the sum of the characters. Keep the storylines diversified and spread across all the characters and it will be a hit for a long while yet.
Phil is hilarious.
