Yes. Liberalism is fundamentally about the social contract, so those limits on speech are compatible with liberal ideals. It is very consistent with liberalism that objective lies are a punishable offense because they are violations of the social contract, similar as shouting fire in a crowded building when there is no fire, a tobacco salesman saying their product is healthy, or an opiate salesman telling doctors their product is not addictive. Of course that's idealistic because the truth in many situations is largely unknowable and the temptation to put government officials above the law is great. Reprisal for false accusations is a chilling effect for those making true accusations. That means there is a balancing act to be done. Both type 1 and type 2 errors are bad. Since America cannot effectively punish lairs, that weakness in our system is being actively exploited to great effect, you can read fox news court documents where they defend their right to lie. Unpunished lies give those who lie power, reduces societal trust, and drives division between members of society. But likewise true accusations must not experience reprisal because otherwise it gives those in positions of power a shield against consequences for their crimes.
