Counterpoint- "the community that will not allow you dignity" is not a homogenous entity. The city of San Francisco contains multitudes, many of whom are compassionate individuals who take active measures to help those on the streets. By pooping on the sidewalk / in front of City Hall / etc., one indiscriminately targets both those who are compassionate and those who aren't.

Furthermore, one isn't likely to create a community that does allow dignity for all, without first winning the hearts and minds of the less-than-compassionate members of the public. And one isn't likely to win those people over by pooping on their doorstep.
