The claim is that it won't create "a right to be offended", because the term "Serious emotional distress" is supposed to exclude mere outrage. Nor embarrassment, anxiety or worry.
It always starts that way, and usually ends at "say anything that offends the ruling party and they throw your ass in jail". On the internet this seems to happen at internet speed, to. Most countries that forced ISPs to block a list of "child abuse/exploitation" IP addresses or site, which of course were not made public, only took 3 years or so before opposition party's material mysteriously was being blocked. Funny how that works.
The only real way to protect speech critical of the ruling party is to protect all speech (we're talking at the criminal level here, not torts for libel etc). Anything else is the camel's nose under the tent.
