Why people are mocking Cameron's Christmas message with 'You ain't no Christian bruv'

David Cameron delivered his Christmas message as festivities kick off up and down the country.

He alluded to the UK's Christian roots:

As a Christian country, we must remember what [Jesus'] birth represents: peace, mercy, goodwill and, above all, hope.

I believe that we should also reflect on the fact that it is because of these important religious roots and Christian values that Britain has been such a successful home to people of all faiths and none.

However, only two in five Brits now identify as Christian.

In fact, a whole collection of people on the internet are calling into question Cameron's own religious beliefs.

Asking whether some of his actions as PM really sit side-by-side with peace, goodwill and mercy with the hashtag #YouAintNoChristianBruv.

People referenced the poor and the hungry

Others suggested there was no room at the inn

What about charity?

The Scottish wanted in on the action

In November #YouAintNoMuslimBruv trended worldwide following a stabbing at Leytonstone train sation, east London.

The prime minister himself even uttered the words during a speech in the Midlands shortly after the incident.
