The far right, emboldened and enabled by political leaders such as Nigel Farage, are currently engaged in a wave of misinformation-driven violence that is in danger of engulfing the UK. See it for what it is - extremist thugs manipulating the totally unrelated murders of children to further their fascism.
They are using the tools of right wing social media outlets to organise and spread their misinformation and hate via the usual suspects - Tommy Robinson, Katie Hopkins, Andrew Tate, Elon Musk etc.
How can we fight back?
One way to effectively fight back is to support groups like Hope Not Hate and their 'Hold On To Hope' campaign: https://hopenothate.org.uk/hold-on-to-hope/ where you can sign up to lend support, keep abreast of developments and donate if you are able to.
If it is safe for you to do so, another way is to talk positively about multiculturalism on your social media presences and challenge the prejudices you encounter.
This country was literally built by thousands of years of multiculturalism with hands and minds from many places and of many colours creating the very best of it. We must never let the far right deny that reality or allow their misinformation to gain a foothold.
EDIT: Here is a list of UK wide anti-racism protests being held this coming weekend: https://standuptoracism.org.uk/stop-the-far-right-national-day-of-protest-saturday-10th-august/
