I think crazies is a pretty insensitive way to speak about people who are likely unhoused and experiencing untreated mental health crises. No hate to you at all but living in a city you will encounter these people often because this is where they can find resources. They are typically not violent and are more likely to be the victims of violent crimes than commit them. It’s just something to maybe be a mindful of when in a city environment. They’re people deserving of dignity and respect just the same as any of us.
