I love that original post, thanks!
More and more it seems that a lot of the holidays were forbidden to JWs just to make them stand out as different from the world.
I guess there is nothing wrong with that as long as you state it clearly. To say that you want people to NOT celebrate something so they can stand out as different is at least honest.
To say that a holiday such as Fathers Day is "forbidden" in the scriptures or that it is wrong religiously with no substantive reason, is dishonest and manipulative.
