The existence of the day is to be sure very much an attempt to promulgate the Cult Of The Founding Fathers by those who are convinced that all Americans would surely agree with themselves if only we understood the Real True Meaning of the Constitution as they do. But you that's alright. C-Day is at worst the least obnoxious display of this particular fetish by far; and I would even go so far as to say that some degree of public fetish towards the Constitution is a good thing. The Constitution is indeed a glorious thing that deserves to be hallowed. Or rather, it happens to be the document on which are written several separate and independent bylaws which are themselves glorious things that deserve to be hallowed. So in honor of the king of them all, the mighty first amendment, here's one act of blasphemy against all five of the major world religions; along with the malicious burning of the flags of several different entities chosen not-quite randomly by myself.
Truly offensive things to non-Abrahamics were somewhat hard to find just over the Google. Which I guess can be attributed to lower overall numbers/existing mainly outside the West. I also restrained from googling outright calls for genocide or the pornography that 'came up' as a result of unfiltered searches for "Fuck -------". Moving on.
