Religion doesn't do anything. It can't - it is a concept. People use religion, but the religion itself can't do anything. People do things, not concepts, concepts can't do anything unless a person interprets and applies it. And many other concepts - science, popular culture, history, philosophy - like religion are made by people and used to pass judgement but they can do nothing without the people - they would just be ideas in the ether. Separating them from the people makes them useless.
When your opinion comes to saying that people, particularly of a different group you don't belong to, aren't doing things right or are missing "the point" of their own religion, culture, or choices, it should be questioned why one should think they are in any position to decide that better than the people themselves. And these opinions often become telling people what to wear in daily life, both in law and in civil situations - it happens a lot and should be questioned.
It's not scripture (where it could be interpreted in is a debate for those communities, not for outsiders to impose), but these perceptions are mostly from popular culture representations of a religion and several cultures, representations that are which are flawed, biased, and homogenizing of over a billion people on the hows and whys they do things. It's like a White American telling an Ojibwe that to wear a traditional item to a civil event would ruin the meaning of said item because they're only doing it for fashion/to cause a stir. Oh wait, they're still doing that now, in 2013, all the time - people have been fined over $1000 for wearing a single feather, been refused their diplomas over a single feather that has a world of meaning to the person and culture involved, but to an outsider they think it is "missing the point" to wear in civil situations and say it's just someone being rebellious/ruining the atmosphere. Their judgement has ruined people's lives because they think they know better about over 500 American indigenous nations and why we do things.
I'm not offended or upset, I just think it is rather entitled to think that someone with no personal involvement would know more about it and are in a better position to judge than the person involved. I would take absolutely no stock in said opinion of someone with no experience and would challenge the attitude and beliefs behind it. Just as I would from a non-medical person who has no experience of my medical conditions trying to give me tips, typically they just come across as a bit silly and very clueless.
