Assuming you fancied them and liked them as a person would you be prepared to go on a date with someone who?
a) was a cocaine dealer?
b) was a govt. assassin?
c) designed weapons?
d) sold weapons to other countries?
e) tested cosmetics on animals?
f) was the offspring of a Tory (if your left-wing) or Labour (if your right-wing) peer?
g) was the lead singer of a band whose music you hated?
h) had killed in self-defence before?
(I mean take each one separately by the way - I'm not suggesting all are the same person)
