I hear where you are coming from but here is the problem. Right after 10/7 the same thing was done to Alica Keys. She had an Instagram (might have been twitter) post with a paraglider in it. Everyone took it to mean one thing. It turned out it had zero to do with 10/7. That is what happens in an EC, you don't question things. EC does not mean you are wrong it means you just accept everything as fact without questioning it.
The picture of blood on the hands has been around and used forever.
You answered yourself. The paraglider thing was unfortunate timing, but it wasn't a historic symbol identified with terrorism and the lynching of Jews. This is not that, and everyone knows it.
I am also aware of what it means to most here.
Also this is disingenuous. It's not about what it means to us here in the EC. It's what
they themselves use it for. I mean, up until US college students decided it doesn't really mean that and it's really about the Palestinian blood on all of our hands, and not our literal blood on the hands of those who actually lynched Jews..
