Is it really against your consent though? They didn't take the taxes without you knowing. Before any tax is passed or increased the public is notified. So I guess we can take the issue of theft away.
Everyone living in this world is paying taxes directly and indirectly. Can you ensure that everyone knows the indirect taxes they pay for every purchase, including small groceries to any luxury item? So let's just assume someone in the metro stole a wallet from someone and due to the crowd the victim is not aware of his lost wallet but it's still considered as theft.
Laws are not passed with everyone's consent, when the government has a majority they can do whatever they want and the remaining should accept it whether they consent to it or not. Taxes are not imposed on only who voted for the winning party, it became common to everyone.
