Birds tend to fly in unison. If there was a bird that didn't fly in unison-the
same as other bird patters-there would be a discord. So, for some animals, in specific environments, likes attract. While in other cases like procreation, opposite attracts. Then you have Spider Plant Chlorophytum that are asexual, so they self-reproduce.
Humans
procreate male and female. Outside procreation, intimacy between two
human beings are natural as we, like a mother to her child, are naturally pulled to
people like ourselves. So in the Bible, sexual sin has to do with an action that goes against what our bodies naturally do. So if a male sleeps with a male as if he would a woman, that's a sin. It has nothing to do with him being homosexual-LGBQS and so forth. It
specifically has to do with actions and intent.
The hang-up over homosexuality,
@Skwim , has to do with wrong definitions. If people get the definitions correct, then they'd see what is a sin and what isn't with no regards to someone's sexual orientation in relation to the sinful action.
