Maybe they should be asking themselves what they have done to deserve being contacted by the aliens of presumably far superior intelligence and technology. The aliens are a busy lot, with their own alien problems, so why should they waste their alien time and resources for some gasbags in Royal Astronomical Society to pat themselves on their collective backs?
The theory behind SETI isn't that somebody might be intentionally trying to contact us specifically, but that we might be able to pick up communications they sent out into the heavens long ago.
Any signal we pick up would presumably have been generated long before the Royal Astronomical Society, or human civilization, even existed.
