Did you possibly mean commendable?

I shall play devil'$ advocate.

The FFRF promotes agnosticism and atheism, and we at Agnostic do too. Isn't a religious artifacts business promoting religion; thereby tending to nullify our effort to be free of religion? In fact you cannot sell to a religious clientele and be free from religion.

Necessity might drive me to do it, but I'd not like it.

It might even be easier to take advantage of them financially because of their beliefs, that you don't share, haha!

I personally wouldn't have the stomach for it, but say you are a vegan who owns a store, or restaurant or is a clerk, chef or waiter... You might choose to sell, prepare or serve animal products, even though you don't partake. It's not unethical to the consumer to be sold a meat product by someone who doesn't consume meat products... Or a diabetic might sell candy, etc.

So, think of a similar situation and see if it makes ethical sense to you. While we might all prefer to have a business that reflects our values 100%, that is not always a good business choice, and each business owner needs to balance their values with positives being provided to the community, if any. (Of course, we here would think that selling religious merchandise might not really elevate humanity, but consumers buy what makes them feel good.)

I personally don't want to spend my days talking to godheads about godstuff for eight hours a day.
I'm crazy enough from their goofball stuff as it is.

DO IT! Don't you think every church in America has answered "NO" to your first sentence?

If you don't someone else will

No you wouldn’t be taking advantage by selling religious artefacts, it would be a straightforward business transaction. You offer goods for sale and the purchaser can decide to buy or not...his decision. That is how commerce works, and you have no requirement to like or endorse the goods you sell in any way. Whether you could stomach the idea of selling them though...that’s a very different question, but not a moral one, just one of principle.

The purpose of a company is to create and maintain a customer. Servicing a market that is needing servicing is completely reasonable. Especially, because this market will exist for at least decades, prolly centuries.

I wouldnt feel one bit guilty. Brilliant. Just like the telepreachers. They are just in it for a buck.

It would not, all sales that succeed target a demographic. It would be wrong to misrepresent your beliefs and very hard to avoid it with all the God Blesses that would fly around.

Only if you claimed it was magical or some mystical shit. I'm assuming everything you'd sell is clearly marked "Made in China (or wherever, but not divine in origin)". You might as well take thier money or some other charlitain will and give it to Trumps campaign.

I see nothing wrong with it.

Provided you don't make any religious woo-woo claims for what you're selling, I'd say this is totally legit.

I have no problem is taking disadvantage of religious suckers. They signed up to be suckers. Doing business would be very hard if everyone was smart. The economy will not work at large.

A few years ago, I started a few online stores to sell Catholic, Hindu gifts and sold a lot of products. made money, have no regrets.

I wouldn’t condemn such. Business is business.
