Who believes in Jewish space lasers?

I think no one. Even the evil fuckwads that say it are just antisemitic dogwhistling.

You mean the death star of David?

They are Chinese Luna orbiting power space lasers, silly

I think the idea is there are satellites owned by Jews capable of shooting lasers to start wildfires

they are "Directed Energy Weapons" (DEWs)

as with these things that often initially sound "crazy", once you break it down into simple specifics it is more just a question of if it's a thing or not, which may be difficult to prove

Jewish

It's said that Jews own such lasers if they exist

space

satellites, these exist

lasers

It's argued such satellites can shoot lasers, which might apparently be a thing

So yeah "Jewish space lasers" could be a thing, but idk if it is
