application to of the fairness standard in news reporting to all news media.
.
banning the use of cookies to track internet browsing.
.
requiring that all paid trolls be required to identify
(a) that they are paid; and
(b) the person or entity paying them, with severe criminal penalties for failure to comply, and cessation of access to the internet for governments or organisations found not to comply.
.
The chances of an immigrant committing a "terrorist" act are smaller than the chance of being hit by lightning.
.
Fearmongering, and scapegoating of immigrants has nothing to do with the problem of internet radicalisation - it merely punishes people who, on average, are more law-abiding than US born citizens, and who on the whole contribute overwhelmingly positively to America's economy and society.

The problem here is internet radicalisation.  It is not a problem with immigration.

Timothy McVeigh was not an immigrant.
Neither was Adam Lanza.
Nor Stephen Paddock.
