No, those are actually quotes and they're there to give the OP's voice. He said "ideological echo chamber". He said "de-emphasize empathy". Those are his words.

You might be reading it differently than I am. I don't see a knowing nod and wink between a liberal writer and his liberal readers about one of them. I see an engineering manager genuinely angry about another worker.

You might want to re-read his last paragraph and ask yourself if the author is mocking the OP.
