not from usa, but genuinely curious. why is "not talking to X journals" disgusting? many people do that because they don't want to be on a journal with an editorial line they don't like. am I missing something about the guy or the story?
Not talking to a journalist because of their political ideology is understandable to me, although this person probably has a very broad definition of what a communist is.
Not talking to someone based on their religion on the other hand is really quite rude, shallow and discriminatory.
How is that so? Race, sexual orientation, gender, age, sure. Religion on the other hand is no different from ideology (or rather, in my view many left/right-wing ideologies are not very different from religions) - they can be chosen and abandoned freely, and they are prescriptive.
