Not all of them tbf. UK and US and French and Spanish and Portuguese and Dutch and German and Belgian flags, etc, etc, also have a very dark history tbf. And we sell them in tourist shops and turn them into underpants. Star of David isn't inherently bad.
It's not the flag that's the problem; it's the unhinged ultra-far-right Israeli govt run by a far-right extremist who's been in power almost 2 decades who is involved in corruption scandals and clings on to power cos he keeps distracting everyone by starting a new war and has made it his life's mission to ensure the Palestinians never have a homeland.
Could've released the hostages and done a deal in the first week. But why do that when you can kill 60K Gazans and bomb it to shit so it's uninhabitable for generations? 700+ days of war. Stay classy, Bibi. Should be in Nuremberg or rotting in prison for the rest of his life. He's an evil sociopath. But he'll prob never get punished. Hopefully G-d exists and there might be justice in the next life for all the evil this monster has committed. But I'm not holding my breath.
