I dont know that events in France will necessarily boost Ukip. Why would it? We have had plenty of "incidents" involving islamic nutters in our own country anyway and will have plenty more.
Ukip aren't racist unless you think the Norwegians are also racist? Ukips policy on immigration and booting out failed asylum seekers and troublemakers pretty much mirrors Norways. Its probably way too late to matter now anyway as we will breed plenty of our own islamic madmen now just as France has. We will just have to live with it
The chat from the BBC and the left in general is one of "anti muslim backlash", which has never really happened in this country and I am not sure it will for a long time. We are pretty tolerant people. We don't mind folk practising their religion as long as they don't make a nuisance of themselves and most of the west is the same .Ironically, the hate mosques get police protection in the aftermath of any islamic inspired incident. Just as happened after Rigby was slaughtered in broad daylight a while back in Woolwich.
Ukip are too late now anyway. maybe if it had been nipped in the bud 20 odd years ago, but theres no chance now.
