Islamism was not developed in the UK, however racist you want to believe we are. It was developed by Muslims, for their own reasons. It exists in Muslim countries, It has taken over Muslim countries.
Jew hatred was not developed in the UK no matter how racist you want to believe we are. Muslims who are anti-Semitic (and clearly not all are), including murderously anti-Semitic, have their own responsibility for that. It comes from their own Muslim self-identity and beliefs.
We don't see epidemics of other social groups who suffer racism going on these terrorist sprees. We don't have a problem with poor white people engaging in these levels of terrorism, despite white people being the majority population, and the appalling prejudice they have faced, especially from the Left and especially since Brexit. The vast majority of those on the terror list are Muslims, despite them not being the majority population.
You are lying to yourself to political reasons when you try to pretend the problem with Muslim terrorism is white people's racism. And its frankly disgustingly offensive to Jewish people to try to blame their murder by Muslims on the poor Muslim people being subjected to racism, (regardless of who your Gran is). Stop making the (murderous) aggressor the victim, simply because they are brown.
That Green MPs victory speech was one of vilest things I have ever heard. Elected in Manchester and pleading for us to remember the humanity of Muslims when it is Jews who are being murdered for being Jewish in Manchester, not Muslims for being Muslim. But clearly, you are of the same mindset. Muslims must always be the victims to you, even when the racist murderers are Muslims, and their victims, chosen for their race and religion, are not.
And you can't make a claim that you do think Muslims have agency and then write an entire post again absolving them of responsibility, in denial of the facts.
