What is the 'Rattle in Seattle' protest?

The group behind "Rattle in Seattle" says they are protesting what they view as religious discrimination and the undermining of First Amendment rights by Mayor Harrell. 

Their anger stems from the mayor's response to a Mayday USA event that was met by counterprotesters and that led to multiple arrests.

'Rattle in Seattle' press release

"On May 27th at 5PM, evangelicals and conservatives are coming together, from across the state of Washington, to stand against the religious bigotry of Mayor Bruce Harrell and the Seattle City Council.

In a show of force, hundreds will rally on the front steps (4th Street) of the Seattle City Hall on Tuesday evening and demand both an apology and retraction from Bruce Harrell for his disgusting comments aimed at bringing harm to the faith community. If the Mayor won't apologize, it's time for him to resign in disgrace.
