If the far-leftists are wondering why they're doing so poorly in the polls, they might take a look at some of the people they elect into public office. Take Joan Collins who, on Christmas Day tweeted "Merry Christmas to all on here except the FF, FG and Labour supporters obvs."
There she is, sitting her spiteful little echo chamber (quite possibly of her own construction since she admits to blocking people) on social media, thinking that this will impress folks. She was criticized by a lot of people for it although she was able to draw on a number of her supporters who attacked her critics with colourful language.
But, with many things, it's not the ones posting she needs to think about. It's the ones who read a tweet like that and
(a) dislike it a lot
(b) decide not to bother posting about it for fear of the abuse they'd get
(c) resolve never to have anything to do with her and her party.
And the next time the far-leftists whine about bias in the media, they should look in their mirrors instead.
