I am in agreement with LOU BOU TO even though this person is probably not on the forum anymore.
Yes, I believe the religion hates Christmas and other holidays because it seeks to separate and isolate JWs from the rest of the world - and especially their non-JW relatives. The pagan excuse is just that: an excuse. Everything is pagan: the months, the days of the week, wedding rings, etc.
I was not raised a JW and when I started my ‘Fade’ the first thing I did was to re-establish contact with estranged relatives. I sent out Holiday cards and it felt so good to reconnect with these people before it was too late. From then on I made sure I celebrated Christmas because I had such happy memories from childhood.
