Ofcourse there are various angles from wich you can look at this question, but to me it comes down to whether civil liberties should be restrained out of solidarity with people, not capable of dealing with these liberties.

If it was about something with wich you could easily hurt many, many people in the blink of an eye, like say, assault rifles, this would maybe make some sense.

But the freedom of the mind is realy another kind of thing.
