Taxation is theft. It's legalized theft, and it has a long historical precedent, but it's still theft. It is the deprivation of personal property under threat of force.
All right, lets make one thing clear. Taxation is theft. The state takes your money under the threat of force. And it absolutely is your money the state is taking, without taxes or with lower taxes you would have more money for your personal use. And if you want to argue that it is not your money but your employers money, then it changes nothing on it being theft, only the victim changes.
Social contract is not a contract at all, I didnt sign nothing. It is a figure of speech.
Now dont get me wrong, taxation has some differences from most forms of theft, namely it is distributed roughly equally and not arbitrary in order to not piss of anyone too much, and most importantly, it is considered JUSTIFIABLE theft (really similar to a starving person stealing a bread or something like that, a lesser of two evils), thats the crucial difference. So I am certainly not some anarchist trying to get rid of all taxes, however I also dont lie to myself about forcibly taking someones money magically not being theft.
Okay, I had to look up the definition of theft to see what would make you think taxation is theft.
theft: the act of stealing; specifically : the felonious taking and removing of personal property with intent to deprive the rightful owner of it
In common usage, theft is the taking of another person's property without that person's permission or consent with the intent to deprive the rightful owner of it. The word is also used as an informal shorthand term for some crimes against property, such as burglary, embezzlement, larceny, looting, robbery, shoplifting, library theft and fraud.
Merriam-Webster's definition of theft includes that it must be against the law; Wikipedia's definition is a bit broader but it does include the term
rightful owner, which, again, is defined by law.
What I find interesting is your opinion that taxation is theft
despite it being legal. You are not the rightful owner of the taxes you pay. It's that simple.
If you consider taxation to be theft despite it being sanctioned by the legislation...
...then logically you should consider killing people in war to be murder, regardless of the fact that it is sanctioned by the government waging the war, and in many cases sanctioned by the international legislation as well.
If you don't, there seems to be a clear double standard here somewhere. And before you say that these are completely different matters - how? If theft is taking a person's property, murder is taking a person's life. If lawfully justified "theft" is still theft, then lawful killing must also be murder.
On the other hand, if you do consider killing in war to be murder, it begs the question why so many people are so annoyed by "their money" being "stolen" and used for social security, but feel perfectly comfortable about the stolen money being used to
facilitate murder and support professional murderers.
