the 1st amendment that protects it legally
Ok, finally I decided to look-up the text of the 1st amendment:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
There is nothing at all that say the government has to make exceptions to accommodate specific religious practice.
For example in 1990, the Supreme Court held in
Employment Division v. Smith that, as long as a law does not target a particular religious practice, it does not violate the Free Exercise Clause.
In this specific case the supreme court decreed that the state could deny unemployment benefits to a person fired for violating a state prohibition (use of peyote) even though the use of the drug was part of a religious ritual.
Although states have the power to accommodate otherwise illegal acts done in pursuit of religious beliefs, they are not required to do so.
This is the same interpretation since the very first case in 1878 when the Supreme Court was first called to interpret the extent of the Free Exercise Clause of 1st amendment.
The Court said: "Laws are made for the government of actions, and while they cannot interfere with mere religious beliefs and opinions, they may with practices."
Coming back to the case from the OP, there is no ground according to USA constitution to create exceptions for wearing headgears in ID photos.
Well i wouldn't so much say that it is a higher belief (though it is clearly higher than something like sports fandom with no effect on most of life) than a clearly different one. Aelf and illram have already posted some very good points. I would add that religion tends to be far more encompassing in ones life than a political ideology or favorite band or whatever you want to pay tribute to.
One can easily make the point that the behaviour of any hard core
otaku has the same depth of religious feeling.
At the same time can be argued that not all the people that label themselves as follower of a specific religion live it with the same intensity as you described.
In short, this is very subjective, not objective.
If you allow exceptions for religious reasons, why not for cultural/ethnic reasons.
And to what limit we draw the line between beliefs that are deemed worth protection and which are not.
Should we allow, for example, genital mutilation in children (e.g. infibulation) on religious or cultural ground?
People practicing it, strongly believe it's part of their religion/culture, is it discrimination to forbid such practice?
The USA Supreme Court has a very clear opinion on similar cases.
Also, this is not exclusive to religions, but more common in them, is the use of symbols. Wearing a kippah is not much in and of itself, but it is a symbol of the wearer's devotion and faith. What would wearing a cheesehat symbolize for a packers fan?
It demonstrate devotion, respect, and alliance to the packers and what they represent in terms of spirit, loyalty, will to win, and whatever else.
Exactly the same as wearing a kippah: it's all subjective.
If the state allows exception for one should do for the other too.
I also don't think it is special treatment. It is simply allowing a person to practice their faith.
if their faith is so important they can make some sacrifices for it... like do not get a driving license because they cannot remove their headgear for the few seconds needed for the photo.
It harms the concept that everybody is equal in front of the law.
One claim to be religious and get away with something that is not allowed to somebody that does not claim to belong to a specific cult.
Being able to wear kitchen gadgets on your head to draw attention to yourself makes a mockery of the process and does nothing else.
That's exactly the point: show how unjust is to allow exceptions to the law on belief reasons.
Who is being harmed by allowing the religious to practice their faith
In the context of the thread I don't think that religious practice is harmed by not allowing photos with headgears: one can continue to believe whatever he wants... just without a driving license.
Allowing exceptions harms justice and the euality of all people in front of the law.
and why do you feel a religion and a political party (or whatever you would like to compare it to) are the same?
They both are deep "feelings" that contribute to shape your morality and behaviour.
Just to make an example: being a (convinced) communist shapes your morality and behaviour to an extent consistent to a religion.
How intensely such belief (religious, political, ethnic, cultural, trekkie, sport fan, etc.) is lived is strongly subjective.
You assume that all people labeling themselves with a religion live such belief more deeply and more all-encompassing than any other type of personal identification.
I don't make such assumption, and I this that law should as objective and equal to all as possible.
I understand your point, but evolution has many flaws. And it is only fair, that with the numbers of people who doubt evolution, that alternatives be taught.
Evolution may have some flaws (which ones btw) but much less than any other alternative.
More importantly the theory of evolution is not an opinion based on books: it's based on scientific method and its "predictions" have been proven over and over again.
While most if not all of the points of creationism have been debunked over and over again.
