I think about this often when it comes to my son(He has not shown any tendencies) more specifically how'd I react if he was and I can honestly say I'd be slightly upset. Though I know I would be supportive. In the end its ultimately thier chioce.
I'm not sure if there's a significant LGBTQ+ population on here, but I'm a part of that community. I don't believe that choice comes into it, because it would be easier to choose to be straight and/or cisgender. Some people's brains develop differently as they grow. There is some evidence for gender having a biological basis (Some journals talk about the chemical makeup of brains), but as for attraction/orientation, I don't know if there's been any research done on that.
Homosexuality, even bisexuality, and more have been around for centuries and throughout history. Those who are gay have existed for at least as long as written history. Calling it a choice, or a 'lifestyle' misses the very real fact that for most people who are homosexual, being attracted to the same gender has been something they have experienced since they were young. It wasn't a choice for the majority of those who call themselves gay or lesbian, it was simply who they were and an aspect of who they are.
As long as those involved are consenting adults, or even teens of about the same age, as relationships are common even as teenagers, it shouldn't matter if the relationship is heterosexual or homosexual. As I have read some point out elsewhere, not on this site, being bombarded with heterosexual relationships in media hasn't turned gay children straight. Princesses and princes, stories of mothers and fathers, and more. It is treated as fine, romance is common even in media directed at children and youth. A homosexual relationship is no more perverse or incorrect than a heterosexual relationship merely for existing.
This thread and the poll bother me, as well as those who do believe it is only or mostly a choice, and it disappoints me many of the comments and replies here. Even for the sake of arguing it was a choice sometimes, who cares? Homosexual marriage, and homosexual adoption, are no more unsafe for children than heterosexual adoptions and often times gay or lesbian parents of a child provide a more loving and safe home than those with straight parents.
Just let people love who they love, it is nothing to be offended by or make arguments of thinking of the children. The fact that a guy loving a guy or a girl loving a girl can be seen as inappropriate or innately sexual or harmful has been a problem. Choice or no, if it is consenting, leave it be. An 'It's a choice' narrative has only hurt those in the LGBTQIA+ community, those trying to live their lives without hate or discrimination by others calling them abominations or that they will go to Hell.
Part os this may not directly relate to what has been said in this thread, but it relates to the question of "Is it a choice?".

Its a mix of both. Some are born with genetic inclinations for this. Some turn because of something happens in their life such as a relationship or abuse when they were young. It all depends. In other words for some it is biological and for others it is psychological. Don't forget there are also those who are bisexual.
