TJ, I think bias is created by a lot of things, but having all the facts isn't necessarily going to alter someones opinion, some things are just too big to get past. I don't know your friends, I know nothing about how they've been educated, the books they've read etc so I can't possibly comment on how they form their opinions. Cromwell is always going to be a contentious issue and it is very much up to individuals to make up their own minds. I don't have to like someone to vote for them as a great Briton, being great does not equate with popularity in some cases but that's another argument.
