It's also much easier to be a Star Wars fan and not feel like you're missing anything. It really only takes ~12 hours of your time to watch the bulk of the canon (six films). You don't need to know the plots of Clone Wars, Rebels, Knights of the Old Republic, Rogue Squadron, or The Thrawn Trilogy to be "caught up."
Conversely, Star Trek's main canon is enormous, consisting of The Original Series, Next Generation, Deep Space Nine, Voyager, Enterprise, Star Trek: The Motion Picture, Wrath of Khan, Search for Spock, Voyage Home, Final Frontier, Undiscovered Country, Generations, First Contact, Insurrection, Nemesis, Star Trek, and Star Trek: Into Darkness. Rough math puts that at 703 TV episodes and 12 films. Assuming roughly one hour per episode and two hours per film, you have 30 days worth of material to catch up on. There's no good "jumping on" point because you won't get the jokes about tribbles, Captain Pike, or "he's dead, Jim." I personally discovered The Original Series about five years ago and I absolutely loved it, but it's just too daunting of a task to get caught up with the whole universe.
Not to go too far off on a tangent, but I'll be interested to see how Marvel handles this issue as their cinematic universe grows. I think they've done a good job so far of integrating Agents of Shield and Agent Carter into the universe without making either one "essential reading" to one's enjoyment of the main film continuity. I hope the same will be true with the Netflix series.
