Welfare vs Charity

This issue bothers me more than anything nowadays, so let's have debate.

So why should a person be FORCED to help someone else? If someone needs help, they can always ask for charity.

>By the way, as far as I know, at least in the USA, you always have the option to refuse charity and welfare.

Seriously? What kind of argument are you trying to make here? Sure a person can refuse to RECEIVE welfare, but what difference does it make when people can and are been forced to pay for the welfare of others without their consent? Does logics even mean anything to you?
