Interesting that the dominant tone of your article is that of racial stereotypes, of "white people" and what they supposedly want and support. Perhaps your research excluded social media of the gathering on Saturday, and that of many other Christian meetings and Buchan meeting for that matter, as it is clear as daylight that Christianity (which includes his following) is one of the most racially inclusive "places" in our country. When last did you visit a church before you wrote this article?
You have it very wrong if you think that now only people are entrusting G-d rather than Parliament. Christians in this country have never stopped praying to our G-d for our government.
Let me ask you this; would you have written an article with this tone if it were people of Islam faith that had gathered? Or if it were only black people at such an event? 
Be honest and say who it is your article is really aimed at, as Angus Buchan has become a soft target for you.
