I guess you could take a look at that same website you are quoting and read the actual in game quote from her.
https://wow.gamepedia.com/Valeera_Sanguinar
"I am neither Horde nor Alliance. What has either faction ever done for me?"
or you know, World of Warcraft Comic: Stranger in a Strange Land:
"She culturally identifies as a blood elf, taking pride in her people's traditions and defending their tribulations and loyalties. However, she herself acts independently of the Thalassian government, and has formally joined neither the Horde nor the Alliance since her introduction but is fiercely loyal to Varian and his son."
but who am i kidding, obviously YOUR opnion matters more than
1. Person working for Blizzard programming a quote as her audio file
2. Person working for Blizzard typing up a quote for a character.
Dont let me stand in the way of the TrAIToR chant.
