Jean Fontaine is the "data lead for South Carolina Moms Demand Action for Gun Sense in America." She lives in Greenville, South Carolina. I'm not sure what a data lead is but I imagine it to be somewhere between a mailing list manager and someone who clips articles from a newspaper.
Ms. Fontaine had an op-ed in the Greenville News regarding a training session she attended in Minneapolis, Minnesota this summer. She started the column by saying:
This summer, I took training in Minneapolis for Moms Demand Action for Gun Sense in America, a nonpartisan organization that supports the Second Amendment. It was created after Sandy Hook to advocate common-sense gun reforms that are straightforward...Either the training Ms. Fontaine took in Minnesota was on how to be a commedienne or she just told a whopper. The Demanding Moms for Illegal Mayors are neither non-partisan nor pro-Second Amendment.
Fortunately, those who bothered to read this screed long enough to comment thought she was full of it as well. There was not one comment supportive of her position.
A quick Google search reveals that Ms. Fontaine is a former educator who objected to constitutional carry in South Carolina when it was proposed in 2013. She also served as a Peace Corps volunteer in Peru in the late 1960s. I'm sure Ms. Fontaine, bless her heart, is a nice person and means well but her advocacy is misguided and dangerous.
