The broad definitions in the poll are too close, since it must involve a greater degree of intelligence than offered simply by religion or ethnicity.
For example - recent bombers (and nutters who might pose a similar risk) who are neither Muslim nor Arabic/South Asian:
Timothy McVeigh
IRA
UniBomber
The Washington Sniper
Bader Mainhof Gang
November 17 (Greeks who killed our military liaison a few years ago)
ETA
FARC
Looking at the link at
http://www.state.gov/s/ct/rls/45394.htm, there are a proliferation of national liberation groups who might pose a threat as well, some of whom are white and Christian.
So therefore, I would rather we were all treated as a threat, than some of my good friends being singled out for race and religion alone, while I might be the one in the terror group.
