uk muslim community is likely to be highly interested in israel for the same reasons people in the uk who care about human rights and the upholding of international law are - we've been round this circle tons of times. when uk politicians who are supposed to represent their electorate stand up and give support for murdering children in their beds and other war crimes, eg. collective punishment, british citizens are understandably outraged.
also in a multi cultural society such as our own where a lot of work and investment goes into trying to create social cohesion we have vested interests in international events where one group, represented in our own population, is exploited and mistreated by another on a hugely public stage. when the government here back that mistreatment and are seen to side with a group regardless of the facts it creates problems within our communities too, of course it does.
whether you like it or not the behaviour of israel towards palestinians over the decades and the ignoring of it by western governments, and sometimes outright support of it, is a breeding ground for radicalisation. radicalisation comes partly when people feel they have zero stake in society, when the powers they see running that society seem not to represent them in the slightest and there seems to be no recognised way to be heard or represented.
when we endlessly have politicians failing to represent their views of their population you get radicalisation or disenfranchisement. if you are a part of a group eg. jewish community, muslim community, white working class poor, etc often that radicalisation falls in upon your tribal identity and there'll be those who are there ready to exploit that - in the muslim community that's where young males particularly become vulnerable to those who prey upon that disenfranchisement to exploit it for their own use. we literally have tons of programmes trying to intervene in that process in schools, in community groups, in police units etc. hence me saying we are heavily invested in this stuff.
lots of british people are massively concerned about the situation in israel be they muslim or not. and just making blanket statements as you have about muslims being violent people or not nice people like 'us', or snakes or whatever else has been thrown at a whole diversity of nations and people on this thread and in the israeli press and politics achieves nothing if your commitment is to social cohesion and creating a peaceful society. it serves an ethnic cleansing objective or one of trying to totally crush a people within your borders but that's not a route most people want to go down here.
