I'm a lefty and in all honesty, I didn't spot it straight away, it was only when it was pointed out that it became obvious.
I wonder how many other people didn't spot it first time round? I don't think it was a given, I don't think I must've been the sole exception.
I was scrolling on my phone, small screen, and read that Corbyn had supported some street art, and my knee jerk reaction was good on him, that's clearly street art, it's not shitty graffiti or the mindless territorial pissing contest that is tagging, street art is a valid artform.
But of course the furore made me take a second look, and then it became clear.
Corbyn's had a solid reputation for years (along with John McConnell) as someone who supports grassroots campaigns, so I'd imagine his knee jerk reaction to a campaign to sign a petition or speak out or whatever to save some street art was to do so, without necessarily examining closely the subject matter.
It's easily done. I did it myself, ie I didn't look too closely at the image in the first instance. And yet Corbyn's now painted as an antisemite, even though he subsequently apologised and admitted that he hadn't looked closely.
Has no one else clicked like or commented on something on social media while on their phone, maybe on public transport or while watching telly, while only half paying attention, and maybe getting the wrong end of the stick?
