I think that is the definition of "progressive", that is, someone who pushes a boundary in order, in most cases, to advance a social agenda. There are plenty of people who support progressive policies. Abolition was progressive. Many view gun control as progressive, as they do universal healthcare. Taken to its extreme, socialism is progressive in nature.
That said, it is the job of the people to say "enough is enough" and "we've tried these stupid policies and they've failed, so lets regress to liberty." The most fair and just existence is one of liberty, which means freedom from slavery, but also freedom from intrusive government. I have no problem with city zoning as a way to protect people (ie, no refineries in my neighborhood), but I am free to move in next to a hog farm if I like. But when Chicago and NYC decide that their gun-free lifestyle is the only acceptable arrangement FOR ME, then they need to hear a resounding "no".
