You're so invested in evil and madness, that no attempt by any sane, decent person to explain any of it to you would do any good.
So in other words, you can't.
If it such a simple explanation, you shouldn't have a problem with it. Let's try again- Homosexuality is evil because .... (Can't say , "I think it's icky" or "God says it's bad")
Frankly, homosexuality doesn't appeal to me, but that's a personal taste thing. Fat chicks also don't appeal to me.
This, of course, is from the sour grapes perspective of an incel, who is in his late fifties, and never been married; and who delusionally believes that it is those of us who have successful, happy marriages and families, with whom there is something wrong.
Except 50% of marriages end in divorce, Mormon Bob. I mean, I guess it works well if you belong to a cult and your whole community will shun you if you try to get out of an unhappy marriage, which is why Utah leads the country in anti-depressent use.
Funny thing, I lived with a woman for 13 years... when we decided it wasn't worth it anymore, no recriminations, no legal actions, we just went our separate ways... and everyone was fine.
Soon enough, you'll stand directly before God, to be judged with what you have done with your life. You'll have the opportunity to tell Him to His face, that He does not exist. I wonder if He'll be amused.
So what if you get to the afterlife and find out that Allah is the supreme being, and you picked the wrong religion.
Or if you find out the supreme being is Amaterasu, the Japanese Sun Goddess.
Frankly, I would be more worried if the universe was run by a deity who is so insecure he needs to punish people who don't worship him.
There are 7 billions humans on Spaceship Earth. Only Two billion of them think Jesus did Magic Tricks. That means all the non-Christians are going to hell. (Or the Outer Darkness, I guess that's what you people believe in)
Of the two Billion who think Jesus did magic tricks, half of them are Catholic, the other half are other denominations. Which means that you believe that 50% to 99% of other Christians are going to Hell for not believing in the right way of worshiping God.
This is long before we get into who was a good person or not...
