The SF-ist recently reported that Mission Merchants Association (MMA) encourages residents to vote Yes with them on Sit/Lie. This means that they feel the homeless should not be allowed to take up temporary residence on the pavement in the TransMission.
Call it a coincidence, but within weeks of the Sit/Lie vote, recent reports by the Mission Local indicate that a homeless man was beaten at a playground in the Mission. Raising the issue of whether or not people like homelessness and suggesting the city vote on it causes many people to articulate their negative feelings about homelessness. It is not difficult to imagine that someone might act upon these newly realized negative articulations.
Once the mind is steered toward a subject and thoughts or opinions are formed, there may not be a counterbalance of education to steer those emotions into neutral critical thinking. One TransMission community organization, on the other hand, has been vocal in the Sit/Lie vote.
Counter arguments for Sit/Lie in the TransMission are provided at the SF FoodNotBombs website.
