Please don’t do this. There is no press suppression (see front page article you posted). The other awful incidents are nothing to do with the protests. Nor is the cultural background of our politicians.
Support for Hamas is abhorrent. Protesting against a humanitarian crisis created by a powerful military is something different entirely. The police have the power to arrest the former, and I’m sure their intelligence is working night and day to do so.
As for the rest of what you wrote: I grew up next to Southall & have lived in London for a large part of my life. My primary school class was majority non-white. I can easily say my life has been nothing but enriched by knowing people from different cultures.
