Should an airline's first-class section be adults-only?

I read this article.

Here’s a small sample of the article:

The “ban babies” from first class—and indeed, sometimes from the plane altogether—proponents’ argument goes something like this.

(I’m quoting without attribution, because I’ve received several emails that are virtually identical.)

•I pay a premium to sit in first or business class and I don’t want my to be disturbed by a crying, screaming or misbehaving child.
•While I understand the parent pays as much as I do, I don’t disturb them by screaming or crying or misbehaving and I should not have to deal with their child if they are screaming or crying or carrying on.
•Some children are absolute angels and some act like they are the spawn of Satan. While I understand a child’s or baby’s reaction to the change in environment is unpredictable, that doesn’t mean anyone should be subjected to it either. A person’s choice to have children and fly with said children does not take precedence over or trump my choice to not have children.

What do you think?
