Agreed. We don't even have to go that far, what about ANY disguised religious symbols. Jewish, Hindu, Islamic, etc. It really doesn't matter what the religion is. I respect all beliefs, but I don't appreciate hidden religious symbolism of any kind be it Christian or non-Christian. No different to me than the knocking on my door to "spread the word."
The KoAlohas i played sounded good. Would I buy one knowing the Religious significance? NO.
You may find that many, many, MANY items you currently possess have religious symbolism of some kind printed on them or incorporated into their design. Religion is a massive part of human history, it's the oldest form of government. I might not be religious, but I understand the importance it has for our society, and how certain people absolutely need it and rely on it.
Also, I don't think it's the same as someone coming to your door. KoAloha isn't trying to recruit you, they aren't coming to your door and forcing an ukulele on you, saying that you must believe. It's just their design. You cannot compare that to your example.
I have to be honest, I find it rather petty that someone would choose to NOT buy a quality product from a company with quality customer service, based solely on the fact that the headstock design, and company logo has some religious significance to the creators. It doesn't hurt you in any way, and it's not like a giant christian cross pressed into the fretboard. It is very subtle, and most didn't even know until they were told about it.
Without trying to be directly confrontational, it sounds more like you
tolerate all beliefs, not that you
respect all beliefs. There is a big difference. I would say that I try to respect all beliefs, but I absolutely tolerate all of them...
Some might even say this is a religious symbol. A silly example, but the point I am making is that you can find symbolism, for anything, anywhere, if you choose to look for it:
