Why do ppl think of bombs when hearing Arabians?

I'm gonna be honest bro I don't know much about Arabians other than the fact that quite a few terrorists have been Arabic

Listen, I know someone will call me a terrorist but listen, Arabs aren't dangerous, but those BITCH ASS TERRORIST KEEP KILLING PPL AND THEY BLAME IT ON ARABIANS AND MUSLIMS! I HATE THEM SOO F**KING MUCH THEY RUINED ARAB'S PLACE
