That is the answer, sorry to say you just don't want to accept it.
Perhaps an example but this time with media. The right wing media is happy and gleeful to twist, misportay, and even straight out lie. The left wing media can't do the same thing because they are beholden to the truth. It's the same thing. That's my last reply.
Yes. You shouldn't be allowed to have a second house to rent out. The problem is limited supply in a given area, and if everyone buys a second, third, fourth house (or townhouse) then there is no supply left for people that want to actually buy to live in that house. Frankly I think it's unethical. There are plenty of other ways to invest your money.
I also don't think this position is limited to leftists, although yes the leftists here have a very dramatic take. I think anyone that thinks about this should see the problem.
