Categories and labels are short cuts. When confronted with more souls than you can meaningfully relate to - Dunbar's Number - 200 app. - you apply heuristics. When bumping into a crowd of people and you pick up the word "Bitcoin" here and "nail polish" there, your brain draws a ton of conclusions what to expect when joining this or that group. You label them inevitably. Humans discriminate all the time and sure, there might be surprises when you end up with the other group somehow but discrimination is ok. Just don't be rude in the process.

Absolutely agree it’s all about being authentic and that’s rare these days!
