Lots of good points in this thread!
I agree that if these things (voting, birthday's etc) were truly up to the individuals conscience as a witness, then every time the question came up about whether it is OK to do these things, the only answer printed would be " These are up to each individual to decide based on their OWN personal bible research." Period. .
There would be no long winded answers that start out saying that it is a conscience matter, then going on to list out scriptures and stories and WT articles about how all these things are bad and evil and if you do them, you are dead buzzard fodder, but you can go ahead and use your conscience and decide for yourself.
The second they go on to give an interpretation under the guise of giving out referneces, they are telling the reader what conclusion SHOULD be drawn, and well trained minds will not bother to go and research the context of whatever scriptures, if any, are used in the actual article becasue all that pesky time consuming research has already been done for them! If memory serves me, the only scriptures they ever really use to attempt to back up their opinion are ones to do with obedience and following commands, etc because there are no scripures to back up things like this.
From what I understand of the bible, if a subject is not directly addressed, then whatever it is wasn't important enough to waste time writing about and each person is responsible to use the grey matter between their ears to decide if it is acceptable to them.
