"I support free speech except the things that I don't like"
What principled political speech should be protected you ask? My answer is investigative journalism.
If you believe investigative journalism should exist and plays an important function in society, you should have no problem with outlets doing that.
Many people more intelligent than you (and me) have spent many decades thinking about this issue. E.g. if you can show in court that KF is defaming someone, you can go after them, or if you can show they're involved in other illegal activities. But "I don't like some of the things they're saying on their own forum" is NOT a valid reason.
