You may find it immoral, but it is acceptable if it is a tenant of their chosen belief.
You mean that people are entitled to repress themselves? Maybe they are. I do not pay much attention to such extreme cases, because they are not to be encouraged, perhaps not even tolerated.
If the individual can't reconcile their activities within their belief, then there are consequences (as outlined by that belief).
I fear that you got it backwards. The consequences are outlined by how healthy the belief is, and how compatible it is with the believer.
Beliefs do not get to choose what the real-world consequences of their practice will be. They certainly
bet and even promise on what those consequences will be, but they do not have such power of determination. That is one of the reasons why a variety of beliefs is necessary and unavoidable.
I am not talking about individual (or family unit) opinion, I am talking about congregational beliefs. And they do have a choice as to whether or not they participate within that congregation or faith.
Except when they don't, such was when they are pressured by family from an early age.
An individual's lifestyle needs to be protected, as much as an institution's belief structure and freedom to observe it.
Protected from what, in this case? From the realization that homosexuality is neither evil nor much of a choice?
This is opinion, speculation and theory, not a "perfect" scientific explanation.
Don't project religious expectations into science, or you will be disappointed and mistaken time and again. Science does not deal with perfection, and you shouldn't disregard it so quickly either.
"Obvious failures" and "no good reason" are completely arbitrary to the observer.
Except that you are wrong.
Religion has a responsibility towards its adherents and towards the greater society. That is not at all an arbitrary call, but rather the basic duty of everyone. Slavery is not "arbitrarily" wrong. Neither is homophoby.
You may feel that way, but someone on the other side of the fence feels they are being made to "conform" their beliefs for an individual. Those beliefs need to be protected.
What do you mean here? Which beliefs must be protected, and from whom?
It is in the very nature of belief that is must be tested against the reality of facts and change accordinging, lest it become sterile and harmful superstition.
Just as the individuals rights to choose to abstain or go to another church/faith should be protected.
That is a false simetry. The rights of institutions are an extension of the rights of individuals, and shouldn't be treated as if they were inherently of equal value. Churchs and faiths only exist, and can only be justified to exist, as long as actual people see value in maintaining them.
There is no
a priori ethical reason not to change or even dissolve institutions and faiths as long as the people involved want to do so.
Comparing slavery to homosexual biasness is disingenuous to the argument. People were forced into slavery, no one is forced to be homosexual.
You miss the point entirely. I am not comparing slavery to homosexuality, that would be gross. I am instead comparing slavery (a cruel human mistake that hurts other people) to
homophoby (which is the same).
People have the choice of avoiding slavery, much as they have the choice of avoiding homophoby. And since both stances are inherently harmful and immoral, they should.
Indeed, but isn't that what people are trying to do when they condemn homosexuality within their faith?
No. They are not protecting their faith, but rather corrupting it.
