Sure, but freedom of speech should be protected from government prosecution or suppression...
Why? That's not fundamental to a functioning society. Its not an inalienable right.
In Thailand, a monarchy, the monarchy is sacrosanct. Who are you to tell them that's wrong?
...to the extent possible*...
...or to the extent that society/community desires... FTFY
Don't get me wrong, in Canada, I think speech absolutely needs to be protected. But there are still limits to that. For example, hate speech should be prohibited.
Did you know "obscenity" is not protected by the first amendment in the US? What does that even mean? It really depends on how society views things. https://uwm.edu/freespeech/faqs/what-is-obscenity/#%3A%7E%3Atext=Speech+about+sex+and+sexuality%2Cprotected+by+the+First+Amendment
In Thailand, they put limits on speech that include not insulting the monarchy. It really doesn't seem that different. (And I won't give you my opinion on it.)
I'm not saying it's a bad idea. I'm saying you can't project your beliefs on others.
