Excellent points yada yada 2!
And you are right, witnesses will THINK they are subjects of God's kingdom by supporting the wt organization. The great crowd does not yet exist and they are not in the kingdom covenant .
It is just lies by the gb to convince witnesses that by being subject to the gb/organization they are being ruled over by God's Kingdom.
In the gb's mind they think that THEY are God's Kingdom in which case they are ruling over the witnesses!
