> since there's nothing much to say on that, they specialize in something else This is not really true. There are plenty of different forms of relativism and plenty of philosophers who have taken a stance in ethics that is consistently anti-realist and published countless papers defending various aspects of that. It's more or less the same argument as "all climate scientists believe in climate change because they have to or they wouldn't be able to publish anything, therefore we should discount what they say about climate change". Except in this case it's even weaker, because a significant proportion (though a minority) of ethicists take this position.
