Patriotism does not equal militarism .
Besides, loyalty oaths are dumb. I had to sign one years ago when I was a grad student in Florida. And look at all the good it did me: I grew up to be a freedom-hating crypto-commie homo-symp objective terrorist premature anti-fascist. Well, at least I can look back on it and thank the Florida state legislature for their financial aid which helped me to become everything I am today.
