I think if everyone stuck to facts backed with empirical evidence, there wouldn't be any posts.
They're called opinions.
Of course. But there's a heck of a difference between "I believe that V8s are the best engine for a sports car" and "V8s are the only proper choice for a sports car". There's an unspoken arrogance in the latter that personally I find distasteful.
But I'll shut up on the subject now.
