To help shed some light on the subject, the Update only clarified "toasting/clinking glasses" ... where are people getting birthdays, Thanksgiving and other declared holidays by various religious and governmental institutions from around the world from this talk? I did not see anything that would change our view of these things in this Update.
I was raised by a mother learning the truth and an opposed father. I was not raised to "celebrate" my birthday not any holidays. When I was in elementary school, some of the other kids would kid me about not getting presents for Christmas - however, they would be a little upset when I would get new clothes for school and they had to wait till December to get anything.
When we had children, since we are both in the truth, we never celebrated any holidays, birthdays, etc. with our kids. They learned from day one why we did not. Keep in mind, that does not mean they don't know on what day they were born, how old they are or when they turn another year older. It does get mentioned when any of us increase our age by a year. My kids never missed or regretted not having a birthday party. It is one thing to acknowledge our age and the date it changes - it is quite another thing to throw a party to commemorate it. There is nothing wrong with knowing your age and the date of your birth and admitting you are a year older. That is not the issue. It's engaging in practices that dishonor Jehovah and His word like are done during birthday parties that is the issue.
As for Thanksgiving, as celebrated in the US, that is a "legal" holiday set aside by the government, based on a religious celebration - not something I want to be involved with.
