Travis_Bickle although not linked to incidents in Southport, part of the current disorder relates to the perceived 'islamification' of the UK, or at least certain areas of it.
Certain sections of society, are growing more and more annoyed/angry/frustrated by a.) it and b.) any mainstream politician's unwillingness to discuss it in detail. They are now being egged on by Robinson & Farage to a great or lesser extent.
I appreciate that Muslims don't represent an homologous religious/social/economic block of people, but from a purely numbers point of view; the number of Muslims in the UK has increased from 50,000 in 1961 to 3.8m in 2021. With a more than doubling of numbers between 2001 and 2021.
Due to the demographics of current immigrants to the UK and birth rates within the general Muslim population, those numbers are only going to continue to grow, and grow exponentially.
Certain sections of society have been and are now increasingly rubbing up against each other (actual & perceived), and it's causing sparks.
The political/social issue is not going to go away.
