Understand that you are willing to pay but that again  the problem with an income tax is only those that earn and income(wage or better , compensation for labor) pay it....Not everyone works... So is it fair to be forced to pay when others do not have to ? So they walk out "benefit" from all public services without paying while you pay . Free ride for the sluggards of life once again. 
Why should those that are fully capable of working and don't benefit from your labor (taxes).
