Mayor Marty Walsh drew plenty of flak, and spawned a trending hashtag, by dismissing the opposition to the city's doomed bid for the 2024 Olympics as "10 people on Twitter."

"The opposition for the most part is about 10 people on Twitter and a couple people out there who are constantly beating the drumbeat," Walsh said Monday before Boston and the U.S. Olympic Committee agreed amid feeble public support and boisterous resistance to spike the city's candidacy.

The mayor didn't name names, but here's some reaction from 10 of the most outspoken anti-Olympics activists on Twitter:
