No, you don't need a reason to believe anything. Nor do you need proof to make a claim: I claim that I believe I'll have sex with Jessica Alba tonight. I can't prove to you that I believe that. There is no proof of a belief.
All these extremely arbitrary rules to get out of saying that atheism is a religious belief. Downright silly at this point.
You don't need proof to believe something. You don't need proof to not believe something. Proof has nothing to do with belief.
Actually believing you will have sex with Jessica Alba tonight is what is silly.
I can't prove you don't believe it.... but come on, you would need a reason to believe it
in order to believe it! And I have no reason to believe you actually believe this will happen. If you were SURE you were going to sleep with her tonight, you'd either have to know her already and be going out with her tonight, or you a rapist, and I don't have any reason to believe you are either of those things.
The entire reason why you don't believe all AA batteries are filled with nougat is because
you have no reason to believe batteries are filled with nougat. ...unless, you do believe this... in which case, I'd like to know the reason why you believe this.
If you are going to make the claim that all AA batteries are filled with nougat, you are going to have to have some kind of evidence or else your claim is easily dismissable. As in, it's a worthless claim unless you back it up. This is the difference between belief (just needs a reason) and a claim (needs evidence).
You are trying to say that beliefs don't even need reasons. This is just ridiculously incorrect. I didn't say they have to be good reasons. For example, you might have been raised to worship the Greek pantheon of gods, which would be
a reason to believe in them, but not a
good reason. There has to be some impetus to cause a belief. Beliefs don't just magic themselves out of thin air.
For example, I do not believe Pluto is made from goat cheese. You see, I have no reason to believe this.
Some people do believe that the airlines and the government conspire together to spray the population with "chemtrails" for some unknown purpose. They probably believe this because of some horrendous psuedoscience coupled with a general distrust of authority. Not good reasons, but they didn't just come up with the idea all on their own. Hell, the first guy who came up with this conspiracy theory probably saw some (easily explainable) contrails at altitude, didn't know what they were, and then came up with a cockamamy bull**** story rather than learn about atmospheric sciences. See? A
reason, but not a
good reason.
However, when these guys make truth-claims that the government is spraying the populous from aircraft, they put up evidence trying to support their claim. Their evidence is BS and doesn't withstand even a cursory review, so their claim is bunk. The evidence they use to support their claim can be used as reasons for why they themselves believe it, but the reasons they believe can be entirely separate from the evidence they try to use to support their claim. See the difference?
When adapted to a religious argument, those that make the claim have something to prove (i.e. those that claim god exists). Those that do not believe god exists are not forwarding an active truth-claim of their own; rather, in the absence of a reason to believe, there is no reason for the belief and thus no belief. Just like those that don't believe unicorns exist. They are not making the claim that "Unicorns do not exist and I CAN PROVE IT". They don't have to. Their belief in unicorns just started at "zero" and remained there.
