I promise that I wouldn't care about those things as long as the person isn't harming anyone.
I shouldn't be expected to worry about whether someone might find a religious symbol offensive or not. It's the equivalent of a member of ISIS being offended by someone wearing religious items and then thinking they have the right to cut someone's head off. At the end of the day the offence in these situations is taken by the extremists. There is no offence given. It's in their PC censor-want minds.
