The problem is not your memory, but the fact that some sections of the UK media print a constant stream of incorrect anti-muslim stories.
There are dozens of examples of much more serious articles, which had to be corrected, but of course, no-one ever shares a couple of paragraphs at the bottom of p4 of the Express - once the front page story is out there, the damage has been done.
Here's an article from someone at the Muslim Council for Great Britain. One quote is key:
"In the past year and a half, more than 40 stories on issues related to Islam and Muslims have been corrected in mainstream national newspapers following complaints I made"
I’ve personally complained and won corrections from national newspapers on than 40 stories related to Islam and Muslims, says the Muslim Council of Britain’s Miqdaad Versi

There's another guy who got fed up and started investigating everything, and discovered that a lot of the "xmas banned" etc. stories came from a right wing "Christian" organisation, which was putting out inaccurate anti-muslim press releases. The Times, Sun, Express, Mail and Telegraph had reported the "Birmingham ban Xmas" 150 times in the 15 years after it first came out, despite it being easily unproved.
