I think people used to think they could make someone straight. They still do given that some still refer to being gay as a “lifestyle” rather than an intrinsic part of who a person is. I don’t really get it. It doesn’t seem like a particularly difficult thing to understand.
That's a gripe of mine really.

Unfortunately, I think it's sometimes routed in the misconception that being gay is an intense dislike and / or fear of the opposite sex.
I had a guy once rather inappropriately ask me 'who was the man that turned me gay' as if some man had crossed me and I'd declared him and his gender the enemy and that I was interested in women as a form of... coping? Rebellion? Misandry?

Such folks believe that they'll be the one to 'enlighten' a gay person.
I remember I rejected a guy once and he countered with "Well actually, I think you're bisexual" as if we were having a vote. 
That is hilarious.
