How do Jehovah's Witnesses reconcile their free-will theology with 2 Thessalonians 2:11-13...?

FREE WILL is just something else that the JWs claim to be believers in but their practices suggest otherwise...If they ACTUALLY practiced free will then it would be a JW free will to be able to leave the religion without fear of being shunned by his.her family...if JWs practiced free will then they could choose to accept blood transfusions not be scared of being disfellowshipped for it..taking into account also that the blood thing is ANOTHER mis translation of theirs as it is abstaining from the EATING of blood NOT transfusing it..completely different issues! and so on and so on with them
