I am a born in JW 3rd generation been lapse for 10 years now but I can honestly say I have never seen a tie with a watchtower on or lapel badges, I cannot say the same about Crosses I don't even practise that religion and can't escape them, from the around the neck, too someone making a cross-shape in the air.
I don't doubt those badges exists somewhere but if a few brothers were foolish enough to do them then it doesn't validate your point unless my next question applies...... Is there a uniform code in the bethel were all the ties have watchtowers on them and people are given lapel badges with watchtowers on them to wear in the bethel as part of their uniform? this is a serious question, If this is part of their uniform like the cross is spread all over clergy clothing in a multiplicity of christian faiths then I will agree with your point.
The biggest point that is missing on this thread is paganism isn't just about origin but also about usage! is something that has pagan origins being used in the same way as it originally intended with those pagan origins?
You can definately say this of the cross it's always been a symbol of diety and worship from it's pagan roots onwards, Now lets look at JW usage of the Watchtower it the symbol on the front of one of their magazine and the lapsed title of the organisation (say watchtower and tract society to average person they'll go "Huh?" say Jehovah's witness and they'll know who your talking about)
I just don't think the pagan arguments on this thread are very strong. You may disagree but i think original post sounds like the appologist trying to drag up a pagan link and comparative equality between the Cross and the watchtower which just doesn't stand up to close scrutiny.
