You cannot wear, exude or produce anything that might be offensive to another person.
If I were to take offence to men's deodorant I would be in a minority and not get anywhere. But if I could get enough people to joing me I could have some legislation brought into effect.
In practice this means that anything legislated against (smoking in clubs, cars with minors etc) should have only come about due to a well supported campaign by persons who are seriously offended. This is not the case, most of these laws come into effect becasue the government is doing what it claims is "in the best interest of the people".
Rather than have my elected officials do what they think is best for me, I would rather vote on such things (Even though I despise smokers).
I saw a guy refused his seat on an aeroplane because his shirt read "fuck off" or something to that effect. I have read about this on several occasions and this is just the beginning.
