Snowflakery begins young. The stories I hear from my teacher-students and friends suggest that it may be absorbed through the umbilical.
Consider the young kindergarten student that has nearly driven a friend to drink after only two weeks of school. Five year old Special Sally finds learning her kindergarten lessons too boring, so she meows like a cat, dances around the room, and in all ways is a behavior problem. Now, Myfriend Myra is equal to the task, but of course little Special Sally is angry that Myfriend Myra insists on proper behavior.
Enter Mr. and Mrs. Snowflake A. Asshat, who cannot understand why little Sally acts out---"because she sits so quietly in front of the television every night unless we change the channel or she doesn't like the program." (Myfriend Myra's dry comment: "I'm not a tv.") In any case, the Asshats contend, it is child abuse to require quiet attention or (heaven forbid) for Special Sally to have to say the Magic Words (Please and thank you, of course). They have accused Myfriend Myra of cruelty for requiring the dreaded D-word (discipline), and have vowed to ensure that she is fired as someone "unsuitable to be around young children."
If Snowflake Sally and her parents are terrors now, while Sally is just-turned-five, be very afraid when she reaches college age. Assuming she or they manage to live that long.
