I'm well known in my friendship group as a bleeding heart lefty, with the rest of them being (I thought) slightly right of centre.
Two of them went on the Tommy Robinson March last weekend. They didn't invite me (naturally), knew what I'd say if they did, but it was no secret with posts on FB etc.
Amoung our wider circle there's been a bit of a backlash. One man of Asian origin posted, not in direct response, but I expect it was in response iyswim, about how upsetting it was to see people he knows supprting this racist march. Now this is the most mild mannered man. Completely westernised in his daily life, supports his parents' customs for things like weddings and festivals. Professional job and a huge volunteer. If we talk about contribution he does much more than most.
I replied with something much more neutral than it might have been about how upsetting it is to see people being sucked in by the hate, even if they believe they were there for other reasons, the undertone is there and you can't support a rally like that without supporting the man and his ethos. It felt important to support this man who must be finding the general atmosphere where we live very uncomfortable currently.
As you'd expect it hasn't gone down well with the people who went on the march, who believe they went on the March in protest at illegal immigration and are not at all racist against anyone who is here legally.
I suspect on the surface, it will blow over, but....
