Homosexuality - free will choice or born with?

I just finished a men’s group yesterday that focused on this theme. The central idea being “homosexuals are sinners , that need to find a way closer to Christ - but we’re all sinners in some way , so they’re not that unique from us”.

I’ve always assumed (and still do) that people of this sexual orientation are born this way, or at the very least are born with a predisposition to this tendency. This created a lot of stir in the group, because a lot of these folks believe it’s their choice, and they actively make the choice to engage in this sin. They weren’t born this way, these folks have outside influence that persuade them into this lifestyle.

My question for you all: why does it matter in the end? If god created us all, it’s hard to imagine god didn’t create an individual with this predetermined tendency. Is there a reason why folks would tend to believe it’s from outside influence instead?

Thanks

Edit: I really appreciate the responses from everyone, and it’s a great debate. I’m not sure why this is getting downvoted so hard though, is it just a sensitive topic folks don’t wish to talk about, or is this question ignorant?
