The UK's response to Donald Trump and the role of social media

Earlier this week, US Presidential hopeful Donald Trump called for a ban on all Muslims entering the US following a shooting in San Bernadino, California, that has been described as a terrorist incident and claimed as such by IS. Quite rightly, he was denounced by the other Presidential hopefuls from both the Republican and the Democrat parties. His main rival for the Republican nomination, Jeb Bush, called him "unhinged". White House Press Secretary Josh Earnest asked the Republican party to denounce Mr Trump, saying that his proposal "disqualifies him from serving as president". Mr Earnest then called Mr Trump a "carnival barker" with "fake hair". Whilst Mr Trump's comments have significantly ruffled feathers in the US, I was a little surprised to see the vehement response to his comments in the UK, where political leaders usually shy away from making comments on US Presidential candidates. So what has been the UK's response to Donald Trump's "unhinged" views?
