>the other side
You've really misunderstood me if you think this is about taking sides.
I would characterise first principles to be things like 'who benefits in this situation' and 'what is the historical context of the situation'. Essentially it comes down to not taking sides and looking at situations from everyones and no ones perspective.
I'm aware that it's never possible to 100% escape ones conditioning and we've all be conditioned in one way or another, either purposefully or not. You really don't need me to tell you that certain people are far more susceptible to their conditioning purely based on the fact that they're not even aware of the possibility that they have been conditioned at all. I wouldn't take offence by anything I said as while I did single out Eastern Europeans it's not exactly a unique phenomenon to any locality, it purely reflects my experiences. I've also met plenty of Eastern Europeans to whom this doesn't apply at all.
