Owen Jones has vowed to quit social media because it is “completely and utterly depressing”.
He said he was tired of receiving endless abuse from strangers and suggested social media is no longer a useful platform for political debate and discussion.
The Guardian columnist wrote: “On a daily basis I have angry strangers yelling at me, on the one hand, that I'm responsible for the destruction of the Labour Party, and on the other, I'm a right-wing sellout careerist who's allied to Tony Blair and possibly in the pay of the Israeli government.”
He continued: “I find myself constantly engaging with people denouncing my motives while sending abuse. And my friends ask: What are you doing? Why are you wasting your life on this nonsense? And they're just right.
“Added with the usual far-right extremists sending ever more creative descriptions of how they're going to torture and murder me, I'm no longer convinced social media is as useful a tool for political debate and discussion as it once was.
“I wouldn't choose to walk every day into a room full of total strangers screaming mindless abuse and making up what I think and what my motives are, but in a sense that's what I'm currently doing.”
Taking a break from social media (except to post articles and videos) because, well: https://t.co/1rZupLlrVm— Owen Jones (@OwenJones84) March 11, 2017
In the 1,115-word Facebook post he goes on to insist that he will “never stop passionately believing in the things I do”.
He also admits that he will still use social media to promote articles, videos and events.
In January, Mr Jones issued an online call-to-arms for an emergency demonstration against Donald Trump’s controversial travel ban.
The event received major attention on social media and tens of thousands descended on Westminster for the march.
