At this point, do people prefer to accept a claim in a lawsuit as the truth if it happens to conform to their model of reality?

When the claim is entirely expected and unsurprising due to being backed by a laundry list of historical similar offenses 5 miles long, yes.

So much of social media (low voted submissions here too) boils down to people fighting over ideological symbols or trying to hear a series of appropriate echoes. If you support the suit you probably "hate Amazon" and if you don't "You're a bootlicker".

The idea that you could not support Amazon or their practices, but also not take this lawsuit as some grand symbol of everything wrong with Amazon and the world is nuance most find repellent online, and increasingly offline.

When it comes to a company known to hire union-busters rather than deal with a burgeoning union in good faith? Yes. Yes they do.
