What is the big deal between consenting people of the same sex, whether as individuals or as a group, having sex? Even if you have groups of more than 100 people having sex, how is that going to hurt others? Most of us are born bisexual whether we realize it or not, and that means we have the potential of being attracted to members of the same sex. The only way it could damage the human race would be if everyone was exclusively homosexual and then because babies could not be born. And that would have taken care of the issue by itself, without joke-hova intervening, because of zero birth.
The same goes for adultery, if it's where the "innocent" party knows about it and you are upfront about it. Occasionally, you get "adultery" where everyone involved is present and participating at the same time. The only time adultery is bad is if you are hiding it from the other spouse, lying about it, and the spouse would not approve. Which usually happens when you get a bad match in your original marriage (which usually, within the washtowel, is the result of wretched choices of spouses or because you don't get to dry-run the marriage before committing) or your marriage is infested with that "third strand". Joke-hova does not strengthen marriage--rather, that thing drains it. Adultery where you go and hide it often results from this.
So, what does the washtowel do? They go around making it difficult to find a spouse. You cannot find a spouse at an a$$embly without breaking some rule, and the selections within your home congregation are usually pxxx poor. Obviously, dating someone outside the cancer is taboo. And this creates situations where bad marriages happen (which are at high risk of adultery where they go and sneak it). And, they have long-term same sex relationships in so many activities. Go to that place they call spiritual paradise, you are bound to get a same-sex roommate. Do volunteer work or missionary work not as a family, you are bound to get put with a same-sex partner for the duration. Go from door to door, find someone that is interested, you will be handing that call to someone that is the same sex as the call. These situations can stimulate latent homosexuality (remember, most of us are born bisexual), especially when selections of the opposite sex are restricted. Then they bash the victim when they fall for someone of the same sex, as often as not the partner or roommate they are assigned.
Or, worse, one of their same-sex children or relatives. You study with jokehovians, the thing that is studying with you introduces you to relatives and their children (including children below puberty, even babies), and you get stuck with one of those children as the "flagship". Invariably, it is same sex because they think you can't possibly be attracted. Remember, we are usually born bisexual, and in the absence of proper opposite sex exposure, such latent homosexuality can come to the front. And they wonder where so much of the pedophile problem comes from.
