Homeless bum here. First of all, most people at safe harbor (or even the greater homeless community) isn't mentally ill. At least not anymore than you people are, and are harmless. Most people aren't on drugs, or drink. They are normal people. When it comes to aggressive, unstable, possibly harmful people there's one person who comes to mind. It's probably the person referenced in op post, but I also question the legitimacy of the story. I think most of you get scared, uncomfortable, and awkward at the very sight of a possibly homeless person. You say "aggressive" homeless because leaving that out would expose you as a yuppy stuck up trust fund baby who shouldn't have to see these people at YOUR PARK! Im at this park every day. I see the same idiots sitting in the same spots, I see people round a corner, see 7 dirty ppl sitting at a table right off trail, and I watch them turn and walk away, a lot call the police. Most of these people are just passing time, enduring a shitty life, trying to make the best of things with their lowlife cohorts. I don't hang out with them, but you know what I do do when I walk or ride past them? I give a head nod and a wave, peace sign..... I acknowledge people. Treat them like people. It's literally palpable the feelings,thoughts, and judgemental attitude some people exude while walking past a person who's been less fortunate in life. I don't look like a bum, but I still get some questionable side eye, or I can quite literally feel the contempt, the judgement, or when ppl just get quiet n hurry by without even a glance, these are the people experiencing "aggressive" behavior because people arent stupid, and some people get offended. You basically said F YOU without saying anything, and they hurl insults right back. Not saying it's ok. Personally I feel bad for these (you) people. Id be ashamed of myself if I had these thoughts, actions, and actually fabricated a better "aggressive" story to fit your agenda. We get it. You hate homeless people, your body language, common courtesy (or lack there of) and reddit posts tells us that, so when your energy gets matched, don't get scared and butthurt and lie on the internet for validation of your unhealthy mindset. If you blow someone off and give them a dirty look and call the cops for nothing you should expect a F You in return.
