How can Britain's divisions be healed?

The country is massively divided on Brexit and these divisions are only getting deeper. Here is when Owen Jones, a prominent left-wing Guardian journalist, went to interview people at a rally for Nigel Farage's Brexit Party. He got insulted and shouted at by almost everyone he was filmed interviewing. The main points made by these people were about democracy but ironically almost nobody tried to engage him in rational discourse and one person even said that the Guardian newspaper should be banned:

The mood at the Brexit rally was one of right-wing anti-establishment anger fuelled by tribal bitterness against anything that they disagree with. Obviously, its a rally and it's the hard-core rather than the majority of party support, but they are the hard-core of a party which is polling very well.

The Brexit Party won't win a UK General Election, but they will probably push the Conservative Party into supporting a no-deal Brexit. Boris Johnson, now the clear front-runner to replace May, has already said that Britain must leave the EU by October 'with or without a deal'. There is no deal that could conceivably be negotiated that would appease the majority of Brexit voters.

The anger and sense of betrayal felt by the people at the Brexit rally is only likely to increase. If the unscrupulous and caddish Johnson walks back on his no-deal promise then Farage and our right-wing tabloids will further inflame these tensions. If there is a no-deal Brexit then there will be a huge recession and people will feel betrayed again. This anger could go in different places but some of it will go further down the well of the nationalist right.
