1. Treason, under our Constitution, is limited to waging war against the USA (Which includes adhering-to or supporting those who are active in such acts).
2. Islam has been in a state of self-declared war against all non-Muslims for 1400-years.
3. Islam requires all of its adult male members to either be personally involved in such warfare
(Jihad) or to "support it with all their wealth".
4, Much (Most?) of all contributions to "Islamic Charities" ends up, as the Koran commands (Please see #3 above) in the hands of terrorists whose program includes attacks on the USA.
5. No believing Muslim will publicly condemn or deny those parts of the Koran or other Islamic teachings which call for such wars---Including against the non-Muslim citizens of and lawful visitors to the USA.
SUPPORTING ISLAM AND ITS ONGOING WAR AGAINST ALL OTHERS (INCLUDING THE USA) IS TREASON
