It is the statists like yourself that want to insert an exception clause that reserves the power to the states to infringe a right of the people that is specifically enumerated as a right of the people.
But congratulations on being the first person ever to refer to me as a leftist, and for doing so on the basis that I read the words "shall not be infringed" to mean "shall not be infringed" rather than "shall not be infringed except at the discretion of the states".
The states DELEGATED a portion of their powers to the federal government. They did not use the Bill of Rights as a secret modification of their state constitutions, the dishonest and irrational rantings of Constitution haters such as yourself notwithstanding.
Mojave must want dope legalized, I can't fathom any other reason for his argument.
