Not sure how normal it is. It occurs, yes. Any zoologists in the house?
If I take the time to find reliable scholarly sources and the findings of which confirm what you would deem normal, what would this mean to you? This is a genuine question.
I disagree, obviously. I believe humans are uniquely different spiritually to animals, regardless of what physicall characteristivs we share.
What is it you exactly disagree with? That we are apes? Does the taxonomy itself bother you?
Genetically our chromosomes are nearly identical with the other great apes; all apes found in the Hominidae family have 24 chromosomes, except humans. We have 23. We have evidence that there was a chromosomal fusion between two chromosomes to create our chromosome #2, hence the seemingly absent ancestral ape chromosome. This is my layman understanding. I'm sure we have a few members here that are neck deep in genetic knowledge and could explain it in greater detail.
And our similarities aren't just genetic, our intertwined history can be seen behaviorally as well. Everything from facial expressions to lying and feelings of guilt and sorrow. We could get so deep with behavioral similarities that it would deserve its own thread.
Here is the argument I’m presenting you. It contains four true premises from the Bible and one premise verified via natural observation (P1-5), to which there is only one logical conclusion (C):
P1 Human beings have souls.
P2 Animals do not have souls.
P3 A soul is corrupt by sin.
P4 Homosexuality is a sin.
P5 Both human beings and animals engage in homosexuality.
C Therefore, either homosexuality isn’t a sin, or animals have corrupt souls and are sinning in the same way human beings are.
If you happen to disagree with one of these premises or the conclusion, please explain why.
I agree with the 5 statements, but don't see how you reach that conclusion. [...] The fact that animals engage in certain behaviours which are prohibitted by God for humans does not logically dis-prove the fact that homosexuality is wrong for humans or that animals don't have souls.
You would agree that animals don't sin because animals were not affected by the Fall of Man in Genesis and did not inherit a sinful nature. So they are completely incapable of sinning; there is no desire to sin so every action they take part in can only be considered good, natural and normal. Therefore, homosexuality, something they regularly engage in, is not sinful in and of itself. So with all that in mind, what makes homosexuality sinful for humans? By agreeing to those five premises, you and I have essentially devalued sin to nothing more than God's arbitrary decision to label it as wrong.
We now need to tread lightly here, because we're taking the concept of corrupt/evil sin from the Fall of Man (via the snake) and labeling sin as nothing more than actions which God arbitrarily doesn't want humans to do; “sin” is no longer an evil thing, it's just a thing God doesn't want one species to partake in. Take some time to really consider it all because this conclusion has serious implications.
Without objective wrong, appeal to emotion is all atheists are doing with their plethora of OT verses detailing moral outrages.
You're partly correct here and it's true, I do want you to feel disgusted when you read about Yahweh ripping open wombs and dashing apart infants. But I'm also asking you to rationally evaluate those verses and ask yourself if a logical and reasonable deity would do such things, or if it's more likely ancient men created a savage war god that supported their behavior. If the latter is the case, then you need to reconsider a lot of things.
