Trailer parks are an example of affordable, community-focused housing, but the term is used as a perjorative because the people look/act different than them.

People online talk so much about the need for affordable, small-footprint, community focused housing that goes against conventional zoning laws. Well, they've literally just described a trailer park, but those same people will use the term as a classist insult.

Not a whole lot to expand upon here, but if there are any good counterpoints or questions in the replies, I'll respond there or edit my post body.
