I would not say there is nothing to worry about - I find the riots nasty and definitely worrying. There is definitely greater hostility towards certain groups: asylum seekers and Muslims for a variety of reasons. There are lots of complexities about this, and some genuine issues too that have not been dealt with, which creates an opportunity racists exploit.

However, I think its very much a minority view. Even Tommy Robinson's "Unite The Kingdom" protest which DHH blogged about and Musk backed etc. and was supposed to be the far right's big show of support was much smaller than many other protests for many other causes over the years (for and against Brexit, Gaza, etc.) in recent years. I also think it likely even a lot of those who joined the protest have far narrower causes (e.g. anti-illegal immigration) than being fully alt-right.
