Same here.  I was "real name" on RMA from 1993 until 2002.  I fought valiantly in the great BJJ is crap Judo battles of the late 1990's. :-)

In 2002 after 9/11 I realized that everything I said on the interwebz was recorded forever.  Nobody knows what the political landscape will look like twenty years from now.  I did not want my words taken out of context in some future "Administrative Court for Loyalty Assessment", so I went as anonymous as possible.
