You see this is part of the problem, this mentality. The clothes a woman wears or doesn't wear is not an invitation for rape or other sexual activity. If a womans dress arouses you - go take a shower, look away.
This is why in Islam men are adviced not to look at women for longer than is neccesary and women are adviced to dress modestly. When either party does not do their part, it stirs feelings amongst people. HOWEVER people have to exercise self control - there is never an acceptable reason for rape or sexual harassment.
