People's views change over time; nothing wrong with that. What's more important to me is when people can admit that they were wrong in the past.
Good point Solace I sorta mentioned this yesterday.
I do give Bonn credit; he's among the group that has admitted such. At least a few have switched sides multiple times and never once admitted that they were ever wrong, even though their belief today would heavily contrast with their belief six months ago.
It's just like having a girlfriend or wife. Many of them (I won't say all) will give every excuse in the world for every situation in the world, when a simple "I'm sorry; I was wrong" once a month would end the argument. Instead it's a bunch of, "well, I remember it a little differently and ... and ... and oh yes, the phase of the moon ... and ...". Makes you appreciate the ones that can admit it. Similar thing here.
