In case why anybody can intuitively tell that this is retarded, but doesn't know why:
1) The vacuum in space doesn't suck. There's just far less stuff. When you see scenes where things get "sucked" into space, it's an exchange of pressure.
2) Space also isn't empty, especially near earth where the ISS and other spacecraft, which are the primary target of these retards, maneuver.
3) The absence of stuff works both ways. Yes, it technically is harder to accelerate without (lots of matter) to push of off, however you also barely have any drag, so it balances out.
