"Death to landlords" is, while somewhat extreme, a sentiment that is shared by a lot of people in Vancouver and Toronto. These are cities that are facing a record housing and affordability crisis with no indication that the government will intervene.

Defederation based on political ideology seems, well, rather harmful to a healthy democracy... Which, given that lemmy.ca is supposed to represent Canadians, is rather harmful for Canada.
