Asking people what they do is the quickest way I can find out who they are. It tells me more about them than they can possibly guess. Very few follow up questions are required to establish a full picture of their character. And the only thing I'm interested in (initially) is their character. I really don't care what their hobbies are, what they do with their time, or anything else - unless it's dancing. :)

When people tell me their jobs, they tell me what they are prepaerd to do for a living. If they're a salesman, It's goodbye. Same with marketing, advertising, or anything promotional. They're contributing to consumerism, and consumerism is contributing to climate change.

If they're unemployed, I'll ask them why. They'll tell me. Many different reasons are unemployed. So my response would be dependent on those reasons. Technically I have nothing against being unemployed. It's great. It means you can figure out a way to earn a living that doesn't cause damage to the planet or to other people.

If they tell me they're a doctor, a psychiatrist or a psychologist, I will politely excuse myself and avoid them for the rest of the evening.

If they tell me they're a business owner, I will ask them what sort of business. If it in anyway contributes to excessive consumerism or puts toxins into air, water, or soil, I will remove myself.

Yes, I judge. The only thing that matters to me fundamentally is whether people take responsibility for others, and one of the greatest ways we do that is taking care of our planet.
