My favorite Xenophobe setup:
"Peaceful Expansionists"
Fanatic Xenophobe + Pacifist
Extremely Adaptive, Rapid Breeders, Sedentary, Repugnant, Deviants
Despotic Empire
Scout your neighborhood and colonize everything you can. Later on your border pressure will allow you to grab even more habitable planets that previously where part of other empires. Have been able to achieve several victories on medium sized maps without a single offensive war with these guys.
