First i'm not a freak and yes the most of the senju can use wood stlye
He didn't call you a freak, learn to read.
And only Hashirama could use Wood Style out of that clan. :| Never seen anyone else to use it, except Tenzo, who was an experiment that landed on shore accidentaly, so yeah.
On-Topic: Naruto doesn't possess a Kekkei Genkai, and Naruto isn't part of a clan. Uzumaki is just a family. :| A clan is something that fights or lives for a common reason for all it's members.
Not much is known of Uzumaki family, neither Namikaze. I repeat, Naruto doesn't have a KG, but he inherited his father's ability to manipulate Wind.
