Before researching this article, I didn't realize that there had been a Clown/Santa truce back in 2002. I guess the LA Clowns didn't get the memo.
A packed bar takes on an entire new meaning when it's packed with
Santas. At some point in Silverlake, a car full of clowns in full
fluorescent make-up with protest signs bearing messages such as "Fuck
Santa!", "Make Joy, Not Toys", and "Santa's Conform (boring)" showed up
to give Santa a hard time, although there was supposedly a Santa/clown
truce back in 2002.
From the Suicide Girls rowdy recap of Santacon.
