Should Father's Day be banned in schools?

Article here. Excerpt:

'A British newspaper reports that thousands of Scottish students were not permitted to make Father's Day cards at school this year, for fear of offending students who live with single mothers or lesbians. Local authorities defended the policy stating that teachers need to be sensitive to "the changing pattern of family life." It is interesting to note that students are still allowed to make Mother's Day cards at school.

I have no problem with teachers being sensitive, but I think this is overkill. Father's Day is just as important to children who don't have a dad in the home as it is to those who do. Even if a father is not as involved in his children's lives as he should be (for whatever reason), Father's Day is still an opportunity for the children to recognize him for what he does do. If the father is completely absent (again, for whatever reason), it is a bittersweet opportunity to talk about the man who helped to bring the children into the world and what it really means to be a dad...not just a father. For boys, it is an opportunity to open a dialog about the importance of fathers and help the young men aspire to be good fathers. For girls, it is an opportunity to talk about the importance of fathers and the qualities the girls want to look for in a future partner.'
