I despise the man and have done so for most of his career — a manipulator of people and opinion who was given much more than a fair shake by interests in the media and politics here in this neo-colonial part of the country. “Neo-unionist” is an apt enough description, as would be “neo-colonialist”.
But nasty and despicable as all that he was done and said has been, doing so while hiding with others behind a fake social media account is the most despicable of all. So many others on the Right and Far-Right in Ireland are doing so, sometimes in conjunction with the Far-Right of the USA, Trumpists etc.
It is understandable that some political activists may have to use a fake account from time to time, because of political repression or because of unreasonable closing down of their sites by FB without right of appeal (e.g in criticising Israel or in supporting Irish Republicanism). But Harris has no such excuse — quite the contrary, he was promoted by the political-media class.
