Thanks to everyone who gave comments and feedback - it went really well.  Lots of interesting discussion from the other speakers too, largely about the threat of the BNP but also discussion around the even more extreme acts of the English Defence League aka the Welsh Defence League aka Scottish Defence League depending on which country they are marching/rioting in.  

All kudos to police in Scotland who told them they weren't welcome and to go back where they came from. Wonderful irony.
