No, i dont think it is.
> He's pointing out precisely that "doxing" the entire population of Denmark shouldn't be acceptable to her
Denmark is a democracy, that is a decision for the electroate to make during an election. In general we give governments rights and abilities that normal people do not have. Where the line should be is up to the voters to decide.
> and that she's literally not accepting herself being "doxxed."
Not really equivalent. I'm pretty sure the Danish survelience plans, whatever you think of them, intend to have some sort of controls against misuse. (Im not saying that makes them good or ok, just that they aren't equivalent to doxing people)
I fear for what our political system will look like when only those who have become completely numb to such threats remain. What kinds people are they, those who can live with hundreds of daily hate messages and death threats, doxing of oneself and family members, having to live with security guards and secret addresses? What are we losing by allowing this kind of "freedom of speech"?
If your morals consist of eye-for-an-eye retribution, then maybe his actions make sense. But I do not believe that that gives us a better society.
It’s still preferable to doing nothing when that politician is publicly declaring their support of indiscriminately violating inherent personal freedoms on an unlimited scale.
