That’s perfectly true. They’re free to opine as the wish. But they are refusing to even acknowledge the facts that are supposedly the basis for their opinions and are making statements, believed by their readers, that are directly contradicted by the facts.
So they can say and think what they want, but they should present it as opinion and not delude their followers by blithely ignoring the facts.
You say this because you're an honest man and not a socialist ideologue.
