Bullshit. You don't need a religion for your opinion to be protected by the Constitution. On religion or on anything else.
Dayam you are still a complete idiot despite me taking you to school multiple times and proving you wrong every single time. Will you ever learn? The Constitution protects you from the government. Even without it, you are free to be an atheist, but you would not be able to argue that your beliefs should be protected from government infringement.
The only way the courts will step in and protect your beliefs against a law that infringes on them is when they are important enough to you that you are able to prove that they place an undue burden upon you when you obey them. That is why the owners of Hobby Lobby won when they filed a suit against the contraception mandate, and why everyone else who holds a sincere belief will also win.
By the way, since you are one of the idiots that think atheism is not a religion, even though there are religions that do not believe in gods of any type, let me point out that words can actually have more than one meaning. The one you should concentrate on when thinking about the law is the third one below, which is why atheism is legally a religion in this country, and why it receives Constitutional protection.
Wait, you do know that words can have more than one meaning, don't you? And did you know that religion is not an exception to that little factoid? The one that is pertinent in the legal world is the third one below.
: the belief in a god or in a group of gods
: an organized system of beliefs, ceremonies, and rules used to worship a god or a group of gods
: an interest, a belief, or an activity that is very important to a person or group
If you simply file a lawsuit, and then argue that you really don't believe the law places a burden on you because you don't have any beliefs it infringes upon, you will lose every single time.
Feel free to run off and pretend you never challenged me, just like you do every single time I prove how ignorant you are.
