Provided they’re not nazis or fascists or sex traffickers or anything like that. There are bad people out there who prey on vulnerable depressed people and they can be really really nice (at first), and they can wear any costume they want, to fit into any subculture. But some subcultures are more hospitable for them than others. Most subcultures are pretty okay, there’s a few where I would potentially be very careful. Just be smart about it, and be vigilant for abusive behaviors, grooming, and other red flags.
