One of the pleasures of the egalitarian faith is that you never really have to pay attention. You already know the answers beforehand. Everyone is equal. End of story. Don't bother me with actual facts.
And the other, of course, is that it makes you morally impregnable. Wanting everyone to be equal absolves you of any taint of selfishness. Of course, few egalitarians actually live out their "values" --which are usually just opinions about how other people should think and behave.
