Why does Obama opose critical thinking in schools about Argon Potium dating?

It is umed Argon Potium dating is very very accurate. Lava comes out of volcanos and the potium decays with argon aculating like clockwork. Problem in recent years known and well observed volcanic situation produced rocks which dated to millions of years old. Rocks made recently from Mt Saint Helens had high levels of Argon from the get go and dated to millions of years. Why does Obama oppose critical thinking such as creationists use in viewing these rather than chanting to students these are very reliable and highly accurate dates when they are not. Creationists challenge the tired umptions of naturalists yet Obama want them barred form clrooms why?
