Mayor in Seattle banning concealed carry

The mayor of Seattle is banning concealed weapons carry even with a permit on and in all city property. Hence I am forming an actual 2nd amendment and concealed carry group here in order to uphold our right to keep and bare arms. Group to actually go to the range together, city council meetings, fund raisers etc. The mayor here has lumped us law abiding people into the same group as criminals here. I received an e-mail from him the other day and the just of it was "i am going to do as i wish it is up to me to decide who and who cannot carry weapons in this city" Group not limited to just Seattle area. If interested let me know. It is time to take a stand here.
