There is absolutely nothing unconstitutional about flushing or destroying a Koran. Flush away!
I am unaware of a fundamental constitutional right to abortion yet unborn children are flushed down toilets daily. A federal judge ruled that individuals have no fundamental constitutional right to smoke tobacco. Why not? I also checked the 14th Amendment per privacy and was unable to locate a right to abortion. So one may abort, cannot smoke, but may burn flags? As I inquired previously, as far as the desecration of the Koran is concerned, why are military personal being disciplined for possible destruction of it and nobody is concerned about the crosses which fall into the dirt after the beheadings?
