> The phrase "making choices" is just semantics for the topic of free will being an illusion.

I disagree. See my response to Layke1123 just now.

> Knowledge is power in society. Does it change your fate? The answer is no

Again, I disagree; see my response to Layke1123 just now. I understand the attitude you are taking; I just don't think it's a good idea. Believing this will cause more harm and more suffering. More on that below.

> I realized they were in fact acting mentally ill because of their belief that people make choices when regarding one's sexual orientation and gender identity.

I'm very sorry you went through what you went through. And how you deal with it personally, in your own life, is of course entirely your choice. But that very observation (see the irony?) illustrates the error in the general conclusion you are drawing from it.

Even if people's sexual orientation and gender identity are not choices they make (which I agree they aren't), that doesn't mean there are no choices at all, period. For example, even if you can't choose your sexual orientation, you still choose who you partner with, and those choices make a difference. And that's not all; see further comments below.

> I don't blame them or ever want to desire they had free will because I would've sought vengeance for the conversion therapy I suffered. Instead I'm glad fate had me realize they weren't to blame but how the universe unraveled and no individual had any power over how they came to be.

First, as your very next sentence illustrates--"I personally don't think that means people should be left scot free when they violate others."--you admit that the matter of vengeance is separate from the question of choice. Whether or not people make choices is a separate question from how we should respond to what people do.

Second, even if your family didn't choose the religion they got brought up in, or the beliefs that religion inculcated in them, they did choose to put you through the ordeal they put you through. They could have chosen otherwise. What's more, they themselves might not have realized that they could have chosen otherwise (more irony)--those very same religious beliefs quite possibly included the belief that they were forced to do what they did, and if they had instead believed they had free will, the ability to make their own choices, they might have stopped to think instead of just acting automatically on their beliefs about sexual orientation and gender identity. In other words, they were blaming you for what they claimed was your choice (when it wasn't), but they were also refusing to admit their own ability to make choices and that those choices affected you. Whatever that is, it is not a simple "belief in free will" and wouldn't be fixed by a simple eradication of "belief in free will".

> I think the social systems just need to change to a rehabilitation system like how the healthcare system treats people that get sick.

But that system is screwed up as well. Homosexuality used to be defined as "sickness"--and the system then forcibly medicated people with sex hormones to "cure" them. (Look up what happened to Alan Turing, arguably one of the best mathematicians of the 20th century.) And don't even get me started on all the other ways the healthcare system disempowers people and thereby makes their condition worse instead of better.

The only way to avoid having people be abused is to respect their freedom of choice. What should happen in cases like yours is that the person themselves should choose how they want to deal with whatever it is they are dealing with. Their family shouldn't dictate it to them. No "system" should dictate it to them. No "system" should label them, whether it's labeled as "sickness" or "non-standard sexual orientation" or "gender dysphoria" or whatever. No system should tell them they need "rehabilitation". If people ask for a particular kind of help or care, that's fine; but a belief like "free will doesn't exist" has always been a handy excuse for others or "the system" to force "treatment" on people and abuse them.
