I have NO PROBLEM at all with charity. Private charity is a wonderful thing and I give my share. Paying involuntary taxes to a govt that clearly pisses money away and is full of corruption is not my idea of supporting society.
I would like to pay for roads, schools, and defense. I abhor paying for many other things my tax dollars pay for against my will.
The problem with govt is its corrosive power. If I deal with most private entities, I can walk away. They can't make me pay for a product they sell in most cases.
With the govt, they can take your income, your taxes and in rare cases, you life.
