The press isn't obligated to take lies seriously no matter how popular they are.

We often use 'denier' in lieu of 'liar' which confuses things.

Holocaust deniers are liars.
Climate deniers are liars.
Election deniers are liars.
Covid deniers are liars.

Lying isn't a perspective.
It's a political act.
It's extremism.
It doesn't deserve 'both sides' treatment.
