Hopefully I haven't bored folks to death with the comparisons I often make between the WWCG and JWs. I can't help but see parallels between the two organizations though, and hopefully some lurkers might see those parallels as well, and realize the JWs are not the only ones with these authoritarian beliefs. So often the defense of 'the truth' is "we are the only ones with this message". Obviously not, the above links are to sites sponsored by various splinter sects of the WWCG, and the wording on the pages could practically be straight out of an Awake! pamphlet, minus the mentions of Armstrong, WWCG, etc.
To those who can't be bothered to read them, I can summarize pretty well: Don't celebrate birthdays because they are pagan in origin, and promote self centeredness, and may lead to a lack of humility. I make no claims to know whether its done on purpose or not, but the end result and message is: be meek. And meek people are likely to do as they're told. Why, if you celebrate a birthday, you might get a little self-esteem...next thing you know, you won't want to listen to anybody. It certainly helps keep the rank and file downtrodden and obedient. On one of the above links, (the first one) the article actually mentions the concept of self esteem, and derides it, saying that instilling such a quality in children only serves to make them selfish.
"Yet, is that not what is being pushed in our society today? A central premise in education and childrearing is instilling self-esteem in our youth, supposedly to give them confidence and motivation to succeed in life. There is no surer method to produce competition and strife!"...
..."A birthday party places all the attention on one individual, upon whom is bestowed attention, praise, honor and gifts. What a boost to the self-esteem! A young child, without wisdom and maturity, might come to expect—even demand—such attention, which could evolve into self-centeredness. Obviously, this could lead to grave, eternal consequences."
