Getting angry isn't helping you.
There are indeed vocal groups who label any criticism of Israel as antisemitic and this perspective is propagated by large sections of the media. You are interpreting what he said as controlling the media.
I disagree.
Getting agitated isn't going to change that.
Listen to the venom in your post 'how the fuck'...'twisted'...'wilfully blind'.
I am not blind to those tropes but I don't believe that is what is happening here.
People should not be accused of something because of a trope related to their protected characteristics.
However if someone's actions indicate they might be guilty of something it is ok to say that.
I'm from a city where there are lots of tropes about gangs and crime. Would it be wrong to label me a criminal because of the city I'm from. Of course not.
Would it be ok to call me a criminal if I were caught climbing out of someone's window with a bag of nicked goods. Absolutely, that's not discrimination.
No group religiously, ethnically, culturally or otherwise is beyond reproach for their actions.
I feel very angry that for a long time, those opposed to Israel's atrocities in Gaza have been labelled antisemitic. I am angry that that accusation is still coming loudly through the media. That does not mean I think someone is controlling the media.
And let's not forget we had a prime minister who referred to islamic women in hijab as letterboxes, black people as having watermelon smiles etc ... I hope you were suitably vocal when faced undisputable blatant racism as when someone says something which, some people are interpreting as antisemitic.
