I'm not sure if I got this right:
This guy wants to travel to a country, which he believes consists of criminals and use the land's freedom of assembly to protest the country's laws which allow him to protest?
Maybe the USA should give in to his to his demands - for a minute.
"OK, we'll abolish our laws here and use islamic juricdiction now! Under these laws your protest is illegal and we are going to chop your head off on the stairs of the White House! Thank you for visiting America!"
