Absolutely ignore them. I will forever vote and say we need to house them and feed them, idgaf. But give them handouts from my poor ass, directly? Hellll no. Negative reinforcement through omission. Begging is not the way. I would rather them rob places and start murdering politicians. This is an entire society problem, not a me problem.
And before anybody calls me selfish, no - it's an issue of ability over scale. I can kill myself to absolutely help and try to fix one person, but it would cost me so, so much. And just like in a zombie game, if there's only one zombie, you can melee or whatever. But if there's a horde, you fix that shit with bigger guns or bring the crew.
What that means is, I'm not rich enough to fight zombies, so I'm walking away. And homeless people can ask me all they want, and I absolutely hold the social right to ignore them like any other person out there begging me to donate to their patreon or watch their ads or whatever they need in society to survive.
Fix the fucking system. Sorry, not sorry, but, capitalism, as it is right now, is not the way.
