There is a homeless man who is asking for food but I am not going to buy him any.
How does neglecting the homeless make you feel?
It makes me feel nothing. I'm fine with tolerating poverty.
It is your choice whether you choose to help those in need or not, charitable acts are not required. But if nobody helped those in need, there would be a lot more suffering in the world.
I want to see a law that prevents homeless from begging people for money.
Your beliefs are allowed, but they are a bit cold and one should be sympathetic towards the homeless and those who are suffering. The homeless begging can be uncomfortable, but you should try to put yourself in their shoes and perhaps you'll understand why they have to do what they are doing.
