If I interpreted your post correctly, the following happened:
Your friend is Indian, but lives in Britain.
Your friend has a facebook page.
On that facebook page, your friend shared a video from Britain First, showing Muslims condemning the police, and your friend also shared a video showing Christian pastors condemning the police.
I came to that conclusion because I checked the Britain First facebook page and didn't find any video of Christian pastors condemning the police. There was however a video about "How the Bible is accurate".

I didn't watch it.
Assuming my interpretation is correct: What is the problem?
Maybe your friend, by sharing videos by Christian or Muslim extremists, just wanted to provide examples of human stupidity being without boundaries. Just because the video about Muslim extremists was taken from Britain First does not mean the video is a fake.
Common sense is another word for prejudice.
