There is a MASSIVE difference between a parent doing their job, and teaching a kid/teen how to handle their emotions and responsibilities, and treating them like a blank slate that exists for them to project their own desires onto.
I don't give a damn who the parent is. Celebrity, politician, some person no one knows about. That child/teen/whatever is their own person. The parents are there to show them how to be a competent human being, not to dictate a course through life for them. That's awful parenting and literally every person I know who had parents like this has problems with their parents and self-esteem. Of course that's anecdotal, but a parent should be helping their kids foster their own identity and paths through life, not dictating it or projecting their own desires onto them. Parents who do that are shitbags, and the grandparents who raised them probably weren't much better (and so on, and so on, etc, I think you get the point).
EDIT: There are some circumstances that involve homosexual thoughts that I would believe someone would seek therapy for. With OCD (or just obsessive thought patterns in general), someone might have unpleasant thoughts about homosexual acts despite not actually being homosexual. Being distressed by this wouldn't indicate homophobia, I think it'd indicate a great deal of confusion for the individual, and so I would certainly support these individuals seek treatment to help with those thoughts.
But that's not the same as being homosexual.
I dont think you have really thought about this all the way through when you say that statement. You say parents are supposed to teach them how to be competent human beings but there is a lot of molding that goes in there. Dont take this as me dogging you, because that is not really the intent here, but think about it. when you have a kid THEY ARE a blank slate. For the first 10 to 12 years of their lives it is your job to mold them. If you didnt and let them learn on their own your kid would probably be dead by 8 no bullshit. Then you get into the finer points of parenting like teaching your kids social cues.
For instance there is this boy named Zack who says he is a girl. My son thinks that is weird and has told this kid that. So should I let him be and think trans people are weird and uncomfortable people? Same thing with gay people, the thought of kissing boys is something that is completely odd to him, and he thinks that is also weird when he sees it on TV. So should he just say what he wants or should I at least teach him that just because he thinks something does not mean he should say it. What about the confusing message of telling the truth but being nice. Lets say a huge person is walking down the street and they call them fat. Sure, its true but completely rude and unnecessary. These are all things that parents have to teach kids and kids have to obey until they are old enough to get social cues.
Saying kid are not malleable and should not be are patently false imo. I dont see how you parent without molding a child to be honest. Them discovering who they are is probably the last 3 years of their childhood to be honest, so 1/6th of their childhood they dont have the faculties to get who they are, or peer pressure would not be a thing. I mean hell, think about it, there are grown ass kids, 30,40,50 year old kids who have no idea who they are, much less competent.
This is really all I wanted to say, I couldnt care less what happens in Maine if I am being honest. It is a long ass ways away, and there is not one fuck I can give that will change what is happening. So the rest would just be being mad for the sake of being mad.
