The image of Trump looks like he's saying "fuck." The event
Somebody saw fit to edit the sign:
I've looked at the Facebook page for the event. It says:
Donald Trump and the reactionary core of the Republican Party are coming to power in 2017 on a platform of racism, sexism, xenophobia, and pro-corporate policies....
The Democratic Party has proven they are incapable of stopping Trump. It is time to build a new party for the 99% based on the united power of all exploited and oppressed people, on movements for social and economic justice, on the belief that we CAN do better than this corrupt and rotten system!
