I agree with radicalnan. I don't hold any candle for Trump but long before he came to the public notice in relation to the US presidency I was already sick of half the country calling the other half 'racist', 'fascist', 'bigot' every time something was said out of their polemic comfort zone. Usually the recipient of the accusation was some innocent and perfectly decent person who did not deserve to be abused thus.
When James Bartholomew coined the phrase 'virtue signalling' in the 'Spectator' on the 18th April I recognised the concept immediately as it is a sort of 'get your defence/abuse in first' measure.
The problem with outspoken abuse is that it drives dissent underground. British people with manners do not 'call the impolite out' on their lack of manners. They say nothing but act when they get the chance. This is, I am sure, what motivated the two consecutive election results and that of the referendum. I am sure something of the same sort was going on in America when the abused 'red neck' and 'flyover state' constituents had a chance to act against their continual abuse by the liberal elite.
So, I suggest, if we don't want Trump, or Brexit or any other extremity we should try to act like well mannered and rational peple who give credence to the views of others.
