It’s clear that they are not against people like you, and that as I stated, they are using the term Landlord more as a job title than as a status of owning a rented house.
Respectfully, I am one of these people and I absolutely include landlords of any size. Economic rent of all kinds are unethical and unproductive, and that includes any landlord that charges more than what a property costs to produce and maintain (still unclear if @luthis is somehow underwater with his property, i’m not sure how that’d even happen) by nature of some arbitrary notion of ownership. The rent they extract is unproductive and exploitative, on top of the problem of them hoarding homes from the housing stock and artificially inflating home prices.
