Choosing to/not to Believe? Not Possible?

[Mr.Obvious]

It's like... If I were to 'choose' one day, to be attracted to other men. That's a silly concept for a straight male, isn't it?
I'd just go: now I choose to want to suck cock all day. I don't like it currently, but I'll just now decide to choose to like it. And then what magically follows; you can't for the life of you knock the dicks out of my mouth.

Attraction. Conviction. Preference. Taste. Sources for Delight and fear.
These aren't things that fall under the realm of 'choice'.
And there is a whole difference between 'conviction' or 'faith' or 'lack-of-faith' which are points of view created by your history and the current information you have on a subject, and things like attraction or taste, which are more 'inate' to us from the moment we are born. (In case of taste, not entirely as you can learn to like food. But I doubt you can learn to like cock in you mouth if you're not into that to begin with.)
