You know there really is only one important distinction:

There's people who know what Star Trek and Star Wars is

And there's the people who can't tell the difference.

Geeks of all fandoms unite! Take up your phasers and lightsabers, beat down the doors of the ignorant masses and make them hear...that lightsabers are found in Star Wars and phasers in Star Trek.

Do not return until they promise to never use "Live long and prosper" as a goodbye after the conversation turns to Death Stars, I mean seriously.
