What does Hinduism say about Freedom of Speech and Blasphemy

The whole controversy in India about Ranveer Allahbadia's joke sparked discussions of what is acceptable speech. I am Hindu but I am also huge fan of Comedy. Which includes Insult comedy, sexual comedy and dark comedy. What Ranveer said was a joke I heard on many occasions from other comedians. It was the most baseline thing a person could joke about. This was nowhere near what could cause national uproar. However, I was very surprised how Hindus were defending his FIR. Stating that "these jokes are western, and this is not part of the cultural values. Or He got what he deserved". I was perplexed at this. Comedy is supposed to be a safe space for people to say ridiculous stuff. I wanted to know what does Hinduism think of Free speech and blasphemy. Many other religions like Islam are criticized for being intolerant and retributionary. But what about Hinduism? Where does morality lie when it comes to speech? If someone says something unsavoury to the public does that necessarily mean he will get bad karma? I came across the story of Shatti Nayanar, a saint who is known for cutting people's tongues for speaking ill of Shiva and Shiva's devotees. I would ask why? Why is a person granted sainthood for cutting the tongues of blashphemers? Cutting out the tongue of someone is not proving them a liar, it's just restricting their chance to speak. And why does Lord Shiva, an almighty Mahadev, need someone to commit violence(tongue slitting) over words. Also, what is the morality behind comedy? I know religion and spirituality advocates for pure thoughts, and pure actions, but what is saying something unserious immoral? For example, I personally hate seeing dogs butchered for food in China, but let's say I make a joke about how tasty they are as a way of satirizing the situation. Did I do something wrong? I'm not advocating for people to eat dogs, I'm just making fun of the situation. You can tell I'm joking. Would that be impure or offensive to say? Please share your thoughts down below. Respectfully of course.
