Jehovah's Witnesses Question

If you're a Jehovah's Witness, this question is for you. So apparently you're supposed to remain completely neutral on political matters. You're told not to vote, you don't stand for the pledge of allegiance, you don't engage in political matters, you don't appreciate our troops, you denounce raising American flags, you will refuse to stand or even leave an arena temporarily during the national anthem. I know this because I have relatives who are apart of this, frankly in my opinion, brainwash. 
(My cousins were trained at age 4 that people who celebrate Christmas and birthdays, or who EVER questions their beliefs, work for Satan himself) 
So I have to ask. You are aquiring all of the benefits of living in this country, from having human rights, to being able to vote, to having troops protect you, yet it's Satanic to support these systems in any way, shape, or form. 
Do you pay taxes? Is that the one thing God is ok with? I just have to know because I really do harbor a lot of anger about this, having SO many Jehovah's Wittness relatives. 
Does this make any sense to ANYONE??? (If my aunt and uncle saw this they would legitimately shun me)
