You'd have to be completely insane to conflate "Linux is bad" with "Arabs are inferior," and I don't believe that you ever did.
Supporting a democratically elected candidate, especially outside of the conference in question, can not be conflated with claiming "Arabs are inferior" at a fucking talk at the conference.
You people are so swept up in ideology that you are willing to immediately jump to completely unrealistic positions, that nobody on the opposite side holds, and sidetrack the original discussion into arguing about the position you imagine that your opponents hold.
You're fighting ghosts to feel self-righteous.
