Philip Anderson of Mesquite, Texas lost both front teeth in the attack; a GoFundMe account to fix his teeth is now past $32,000, and offers are coming in from dentists to fix his teeth for free. The 25-year-old Anderson has pledged to spend the extra money on planning more rallies.
In an interview with the I-Team's Dan Noyes, Anderson tried to distance his rally from the controversial Proud Boys, who have been labeled as a hate group by the Southern Poverty Law Center. But in recent social media posts, Anderson identified himself as a Proud Boys member. He says he planned the event to protest social media companies who have banned or suspended conservative voices.
The suspect, 35-year-old Adroa Anderson, lists Watsonville as his home, as confirmed by the The San Francisco Police Department and DMV records obtained by the I-Team.

However, on his social media, he appears often in and speaks fondly of the West Oakland neighborhood or "Dogtown."
Adroa is a rapper and graphic artist who uses the nickname "Doggtowndro." He has posted rap and spoken-word videos about police excessive force and racism. He is also seen speaking at and marching in recent BLM rallies.
In one video, he takes a Blue Lives Matter flag from a car and burns it. In another, he picks up dog feces and throws it in the back of a pickup truck with two Trump bumper stickers.
