Around 7 p.m. Saturday, police say a man, who is white, began shouting demeaning questions at the women in the group, such as how many husbands they had.
The men in the group tried to intervene and asked the suspect to leave the group alone.
Police say the suspect then took an aggressive fighting stance, according to police, and told them he was going to get a gun and "shoot them all."
Members of the targeted group called 911 and police arrived within minutes.
The 52-year-old man was arrested for investigation of malicious harassment, the state's hate crime statute, and booked into the King County Jail.
