I think it’s put up as a joke.
Just like the "AW geez, not this s___ again". However, the anti-flouridation supporters had a point about state coercion, then and now, that became muddled with baseless conspiracy theories, in the 1960s about the Communists and more recently about the Bildebergers or whatever. The valid point is that the state should not impose fluoride in the water system when some people may not desire it in their water. Water supply has generally been a state run monopoly; you can't just switch to another supplier as you might do from Coke to Pepsi, or from Wal Mart to Target. As a result, the state should not impel people to consume fluoride when the alternative is to force those who don't want it to buy bottled water or invest in filtration systems.
However, my point is still valid. On a large number of issues, such as police, judicial, or CPS overreach, homeschooling and school choice, support for NAFTA and similar agreements, and abolition of the income tax, you will find any number of FReepers who support the status quo even if past liberal legislation or court decisions are the reason for that status quo. Conservatism in the American sense was once grounded in individual freedom, limited, Constitutional government, and national sovereignty and independence. To too many posters, conservatism has become nothing more than a defense of the status quo and a cheerleader for big government when its power is used for their particular agenda.
