I don't think 'hard right groups' are a great problem. They occasionally come out of the woodwork and gain undue prominence but their influence is negligible and they are best ignored. Far more pernicious in the UK at least is the apparent increase in those who believe that making racist, homophobic, etc remarks is acceptable on the grounds that to do so is 'politically incorrect'. The practitioners of such nonsense are always deeply tiresome, witless individuals of the first order.
