Why should someone change their opinion/view on a subject that they think is right to them ? There are still many of us who are not members of the " herd mentality ".
I have certainly changed my opinion ion on the B word recently. Having been a staunch Remainer I now think we should just get on with it and mop up the consequences!
This is not about Brexit! You have just proved my point. This is about people thinking things through and if anything is about how set in their views many on this site are. And it reflects how hard it is to change opinions.
