You mean apart from their financial and personal incentives? No, not much else. I'm sorry, at some part you draw a line. My line is disparaging the clock that's not even right twice a day isn't considered ad hominem.
Same reason my source about racial discrimination isn't Stormfront, and my source about startups isn't Vox.
Also I wouldn't take what Breitbart has to say about sexist issues at face value either. I'm expecting you to be able to learn that soon enough, I mean you'd give me the same treatment if I shoved a bunch of Daily Mail articles at you. And rightly so.
