What I am about to say is not to anybody directly. It is for everybody to read if they want to. I am not saying that being gay is bad, because it is fine. Some people are gay and that is fine.
Imagine thinking that being gay is the most important thing about you, or the biggest thing in your life, that you would run away from the school of the Gods and spiritual advancement just because a couple people think that anal sex is physically unhealthy? What a joke. Especially when what was said is not even any official religious or spiritual statement and is only an opinion by literally a few people.
If you want to leave, then leave. I don't understand people threatening to leave as if it is an attempt of blackmail to force someone else to change their beliefs to get you to stay. At least from a longer term member it means more than it usually does for the people who usually say this kind of thing, who are members for 2 months or less. But it still means nothing.
Imagine the clownshow of thinking that being homosexual is the focus or the highest description of your entire life, that this is sacred or meaningful above all other things and even above learning, spiritual growth and advancement. There are many gay people who are deeply boring and uninteresting who claim that the state of being homosexual is literally their only and entire personality trait, because they have no personality or interests in any other thing.
I am heterosexual. Being heterosexual is not my entire personality, and it is not my only interest. It is one of the least important qualities or description about me, it is not one of the most important. Being heterosexual is not more important than spiritual growth and advancement, it is not more important than learning, and it is not more important than the Gods. Being heterosexual simply is not important and does not matter, just like being homosexual is not important and does not matter. If whether you are attracted to a man or a woman is anywhere near the top of the list of what is the most important thing about you, you need to basically get a life. Get some hobbies, learn some skills, learn about things that interest you, develop some talents and abilities. Learn a musical instrument, create artwork, learn a new language, practice cooking, learn about electronics or whatever else. But please develop some kind of skills, interests, or abilities. Do some kind of fulfilling work that is beneficial for yourself and beneficial for the world. "Get a life."
A homosexual person should not leave from here because literally a small handful of people think that some gay actions are physically unhealthy. A heterosexual person should not leave from here because a small handful of people think that that is bad somehow. People should not be wanting to leave from here over just the smallest and most insignificant differences of opinions with any other member. The only thing this shows is a lack of personal confidence. If you are right and you know that you are right, you would not fear anybody disagreeing with you about some small thing because they are wrong anyway. Or if you want to follow the truth, if you want to learn to actually be very smart and correct instead of actually being ignorant, wrong, and too unconfident to admit the truth, then you would enjoy speaking with people who disagree with yourself. You would enjoy speaking with people who have different ideas, different opinions, and know different true facts and valid information that yourself might have never heard. If you are right, you can teach the other person and now you both can be right. If you are wrong, you can learn from the other person and now you both can be right. The only possible negative outcome is by somebody being too closed minded to listen to what anyone else says, and refusing to participate honestly in the conversation.
