Guest says, "I prefer people that stick to their beliefs over people who change their positions to suit the occasion."

I think you mean you prefer people who stick to their beliefs even when they realize they are wrong.

I think there is nothing wrong with admitting you might have a made a mistake and changing your opinion based on current information.

In fact, Guest, thats what intelligent people do.

Stubborn people "stick to their guns" in spite of relevant information. Thats called pig-headed obstinance or just plain ignorance.
