Xenophobia

[Tallis Rhul]

The Founders, for sure, they hated everything they didn't control.

The Tholians could be argued to be as, or more, xenophobic, but I think it depends which way the wind is blowing at the time. Looking at a variety of sources, they're either extremely xenophobic or happy to associate with the Federation (The Tholian Ambassador gave Sisko some Tholian silk for Kassidy if I remember rightly).

(Off topic: More Tholians please! Not enough about them in any of the series!)

8472, bar none. The Founders through the Dominion were at least willing to let other species live as servants (Karemma, for example), but 8472's entire modus operandi was "kill everything."

Don't you think the Founders and Breen getting together contradicts the idea of either being xenophobic? I thought xenophobic implies not wanting to have anything to do with any other people AT ALL under any circumstances. These people wanted to conquer other races. I thought xenophobes just want to be left alone isolated from all others.

It'd help if anyone, including the writers, knew why the Breen joined the Founders at all.

Anyway, I would say, perhaps, the Borg--while the Founders were dicks, and wanted to control everything that wasn't them so that it couldn't hurt them, the Borg Collective generally couldn't stand the idea that anything was not part of them at all, and sought to create a universe that was part of itself.

I say "generally" because the Borg were never as consistently written as any of the DS9 species...

Founders for the win.

I'm gonna have to go with the Founders. Their paranoia and persecution fears feed their xenophobia. They were persecuted, and began to think 'why do they fear us?' Essentially, they began to think that the solids were afraid of them because they were so superior and didn't want to accept their betters - so the Founders began to force that acceptance on them.

Those aliens in "Clues" (forgot what they're called).

Paxans. That was my first thought probably because that's what Data referred to them as.

The Romulans are pretty xenophobic. They have a vast empire yet only allow Romulans in their military. But then again they allow human defectors to live among them (Face of the enemy TNG).

The borg aren't xenophobic they don't fear what they don't understand. They simply wish to assimilate it to better themselves albeit rather grusome way.

Founders are proactively defending their species.

Species 8427 is the most xenophobic because their agenda was simple. The weak must perish. Meaning all life apart from species 8472 must be made extinct. The founders were willing to let other lives under their rule and the borg still allowed other races to exist as drones
