Being judgemental isn't really as much a sin as people make it out to be. It's how you make those judgements and what you do with them that's important.
I'm not going to write an essay here so I'm just going to give a bit of advice that applies to everyone in every scenario, not just Discovery. Figure things out for yourself. Don't fall into cliques and let them group-think for you. Humans (unless they're broken, like me), are social animals by nature, and that's okay. Discovery would be pretty boring if that wasn't the case. But just because company feels good and is fun to be around, does not make them the best judge of character. People become exponentially dumber in numbers.
