I used to do a car share when I was in my twenties with a Muslim women who supported extremists. She was very open about her views and we had long conversations about it. This was over 20 years ago, not long after 9/ 11. Her views were very radical yet she held down a normal, respectable job as a solicitor.
I haven't seen her for years.
We do not have to pretend things do not exist when they do.
I had another female Muslim colleague who went to a catholic high school who held entirely different views.
Not all Muslims are terrorist sympathisers, not all Muslims are rapists and involved in child sexual abuse, but some are.
And pretending these things do not exist or talking about the fact that they do does not make a person racist or right wing.
I had a friend from university who was later killed in the 7/7 attacks, she was one of the unfortunate people on a bus in the wrong place at the wrong time. This doesn't mean that I hate or hold all Muslims responsible. I am very glad that by this time I was no longer involved in the same car share.
