But, if someone is stupid enough to have sex with an obvious stranger, I'd have to suggest the old caveat emptor applies. Your post seems to be an effort to legitimize the one night stand, and not have to deal with the consequences of the stupidity (not you personally, but the normal hetero male who got himself into the situation).
I agree with dmz. If you have drunken intercourse with a complete stranger, you're a dolt.
And if a woman is stupid enough to dress like a slut, does she deserve anything that might come to her?
I agree. Moreover, lying is no grounds to hurt someone. If you really feel violated, seek civil recourse in court. There is no good reason to hurt someone for that. You made a mistake, deal with it in a civilized way. If someone mugs you or attacks you, you kill them, but no way for this. Murder is a sin, and killing someone for misrepresenting themselves it not self defense. It is assault or murder, and you then are the threat to others, and should be punished.
