Your post seems like an example of what GP is talking about. A source being biased doesn't mean it can't make a valid point, nor does it mean that MSN can't do their own vetting.
No it isn't. The GP accused the flaggers of flagging it for ideological reasons, because it goes "counter to their narrative." I'm saying that it's legitmate to flag because it's been posted using the wrong url, because awareness of the true source and knowledge of its biases is useful for evaluating the content.
I would say Rent Control causes more harm than good overall.
It's a failure but people wish it to be otherwise. They wish for things to spring out of the aether by wishing it so.
