Is deism the only belief system that doesn't have an issue with homosexuality?

I think a belief system needs a codified doctrine before you can say whether it has, or does not have, a stance on anything unrelated to its core.

@ragingloli I disagree. Certain social issues and civil rights issues are not only inspired by theology, but theological interpretations. These interpretations are shared amongst communities or groups of particular religious or spiritual persuasions.

Now if you take communities like the deist community and indeed the atheists community. Which in my opinion have some very significant similarities. You will notice some very different types of attitudes as compared to their opponents of organised institutions. You go on any deist or atheist forum on the internet, and you will see the vast majority are in favour of not only LGBTQ issues. They also tend to be pro-choice, and not very conservative.

I would argue that collectively deists, are very pro LGBT (I would claim the same of atheists).

I am also claiming that the opposition or support of many civil rights issues is not directly attached to a doctrine or holy book. But also to the shared ideals of a specific community (be it a church, reason rally, online group etc)

deism is not really a belief system

This may be said for not just deism, but maybe any “non organized” religion.
I have often wondered if an organization’s possible goal of being as large as possible has something to do with most organized religions being against homosexuality.
Since homosexuals are not (or were not) likely to reproduce, they are less likely to help “grow” the organization. I also believe this is why birth control is frowned upon in many religions or why many are encouraged to have as many children as possible.

I don’t believe that the bias against homosexuality originates with religious doctrine. It’s much more likely that strictures against gays are incorporated into religions to legitimate prevalent aversions. Once legitimacy is conferred on such biases, persecution is rendered a moral (legal) imperative.

It does seem that the vast majority of religions “have a problem” with homosexuality. Even some of the more notoriously liberal ones still take issue with homosexuality. That’s why I’ve often referred to it as the “final frontier”, since it seems to be dead last in acceptance. I haven’t met many deists so I can’t really answer the OP, though.

Insofar as Buddhism is a “belief system”, it doesn’t distinguish between homosexuality and any other form of sexuality.

Aside from those branches of Buddhism whose monks (as opposed to laymen) refrain from any form of sexuality, Buddhists are simply directed to not use sexuality in a way that causes harm. That has nothing to do with sexual preference.

The Unitarians.

@NerdyKeith
I am saying that, because without a codified doctrine, all you can ever say is that a certain number of members of that belief system do not have a problem with homosexuality. It does not follow, regardless of whether the number represents a majority, that the belief system itself has no problem with it.

Example: There are a number of christians that have no problem with homosexuality.
Now even if that was a majority, that does not mean that christianity itself is fine with homosexuality,
because the doctrine that defines christianity is quite clear on that matter:
Homosexuals must be killed.

@ragingloli Ok I get you.

But while deism has no coded doctrine there is still basic tenets of a belief system of what deism is (mostly based on definition). So based on that definition, there is no opposition to homosexuality.
