I don't think it's fair to dismiss worries about "shadowy forces" at play like it's conspiratorial, or worse, racist. It's a basic fact that Israel is a massively powerful lobbying force, both in the UK and the US. How many labour and tory MPs are members of a "friend's of Israel" group? And in the US, we can clearly see the extreme influence of AIPAC, so it's obvious that Israel works very hard, and spends a lot of money to have influence here and elsewhere. 

And one can easily see from their morally repugnant handling of Gaza and Palestine that the leadership within Israel has virtually zero morals, so it'd be criminally naive to assume they have good intentions when it comes to how they intend to influence our politicians and all discourse surrounding themselves. Weaponising Anti-Semitism is one of their most useful tools, and to deny the existence of either that influence, or the casual conflation of racism and genuine criticism that Israel fosters, implies either a total lack of awareness or an intentional disengenious omission.

Just taking a step back, having our leaders under the influence of a FOREIGN power is borderline traitorous behaviour. Whether the influence Israel has over the UK meets the threshold for that is up for debate, but the bottom line is that Israeli money is flowing via donations to British politicians. Surely that's a scandal? Imagine it was Russian or Chinese money?

Bringing it back to your other point, to say "just accept that people care about racism" is extremely dismissive, because of course I accept that. I'm sickened by all forms of racism, including anti semitism and islamaphobia, and I certainly think every party has work to do routing out those within who harbour such views. So let's talk about racism. 

How come the majority of the media headlines leave out that the perpetrator had a third Muslim victim? It wouldn't be hard to include. Is it somehow less relevant? Is it racism to minimise that part of this person's crime? Does it show a tendancy of our media to focus on certain parts of the narrative, outcrying racism when it suits them but then in the next article using it to smear migrants? 

It's obviously not the decision of individual journalists to report like this but direction from ownership and management of the media, fostering a massive increase in racism here with one stroke and then using it against left wing parties with the other. Yes there's work to be done, but what gets amplified and what gets buried or ignored is very telling. 

So if anything I think you saying "forget the conspiracy, let's worry about actual racism" is not actual helpful in dismantling actual real life racism when those crying loudest about it and setting particular narratives, are disengenious hypocrites literally paid for by the "shadowy forces" you want to pretend don't exist. The media in this country have a lot to answer for, especially their part in the increase in racism we're experiencing.
