Over 100 prominent members of the Star Trek cast and crew have written an open letter against Republican presidential candidate Donald Trump.

The letter, which was posted to Facebook on Thursday, trumpets:

Star Trek has always offered a positive vision of the future, a vision of hope and optimism, and most importantly, a vision of inclusion, where people of all races are accorded equal respect and dignity, where individual beliefs and lifestyles are respected so long as they pose no threat to others. We cannot turn our backs on what is happening in the upcoming election. Never has there been a presidential candidate who stands in such complete opposition to the ideals of the Star Trek universe as Donald Trump. His election would take this country backward, perhaps disastrously. We need to elect a president who will move this country forward into the kind of future we all dream of: where personal differences are understood and accepted, where science overrules superstition, where people work together instead of against each other.

The letter goes on to say that voting Green or Libertarian, because the two major candidates are “equally flawed” is “illogical and inaccurate.”

The letter is signed by many notable members of the Trek family across the various series, including Scott Bakula (Capt. Jonathan Archer), LeVar Burton (Lt. Cmdr. Geordi LaForge), Terry Farrell (Lt. Jadzia Dax), Chris Pine (Capt. James T. Kirk), George Takei (Lt. Hikaru Sulu), and many others.

“Vote for a future of enlightenment and inclusion, a future that will someday lead us to the stars,” the letter concludes.
