I'll ignore the blatant spelling and grammatical errors ("Quiet" is an adjective, "quite" an adverb--whoops, just said I wouldn't do that) in favor of the more insane mistake here.
To wit:
1. People who do not believe in Santa Claus, nonetheless still write about him.
2. Even the kid on the playground who says, "There is no Santa! It's just your parents," doesn't hate his parents or the concept of Santa. Kids love getting presents, and most non-believers-in-Santa (i.e., grownups and older children) still find the idea of Santa to be a pleasant one--a reminder of the joys of the holiday season and of the carefree innocence and simplicity of youth.
3. Anon's last sentence is along the lines of "People who tell their kids that the man in the mall isn't Santa Claus are just saying that they believe in Santa Claus, but hate him."
The analogy fits perfectly: To children, Santa Claus is a very real being, who is personally experienced at malls around the country, and who provides incentives (in the form of presents) to be good.
To Christians, YHWH is a very real being, who is personally experienced in churches and prayer groups, and who provides incentives (in the form of Heaven and Hell) to be good.
To adults, Santa Claus is a pleasant fantasy, created to make life more enjoyable and to keep children in line. Most atheists have a similar view of God: a pleasant fantasy created in order to give people hope and keep them in line.
Also, if minority groups "just stay quiet," nothing changes. Should Rosa Parks and MLK have just stayed quiet and gotten arrested? Should the suffragettes have just stayed quiet and remained disenfranchised?
