I think the fact that Americans have trouble understanding how one could express the full range of political ideology while still remaining civil and not bullying each other is part of the problem. One can express any proposal for legislative or judicial course of action without demeaning the inherent humanity of another and resorting to profanity, lewdness,and hatred. Learning to express opinions in this way can hel…
And again, what happens when people claim that a certain political view inherently demeans humanity of another? This is already the case: people already proclaim that some political views are inherently dehumanizing. Invariably, those in power will enforce these restrictions against their opponents to their own benefit.
I admit though I can't think of a good way to legislate the nuances of someone expressing an opinion that one ought not to be able to compete in sports of a gender they believe they belong to, without making them feel they are being dehumanized.

On the subject of what led to this law, my girlfriend and I were avid watchers of the show Terrace House as the events that led to this person's death unfolded.
The girl had been quite rude to a foreigner on the show.
This was considered a huge disgrace to the nation of Japan, to have one of their own act so meanly to another, especially on as international of a platform as Netflix, especially to someone from what is considered a partner country, like the U. S..
This led to social ostracization where many Japanese were (civilly) telling her that she was no longer respected in general society, and questioning the extent of her ability to behave with civility.
I believe this (civilly said) cultural censure for her imopliteness likely contributed more to her feelings of worthlessness than any truly hateful and ignorant things said to her. Or maybe because she grew up in Japan she was just not emotionally prepared for hearing some of the hateful things people can say on the Internet (this is the public narrative).
Either way, it's a tricky situation, and many in Japan felt she was actually the one who began the degregation of civility with her behavior on the show, but none the less the resulting way people spoke to her was also not considered acceptable.
How can one balance expressing the idea that she brought shame to the nation while also not making her feel dehumainzed? I don't know. But I'm quite sure in the minds of the Japanese who wrote this law, the main thing they want to avoid is people telling others to kill themselves directly or cursing at them, rather than avoiding expressing judgemental ideas on one's behavior, which is common enough in Japanese society, to be subtly hinting at one disapproving of the behavior of others, while remaining civil.
