So, the "extreme" is that they look on social media now.  Thats pretty much it.  Nothing else in there is any different than what we were already doing before.

Again, this is a knee jerk reaction to NOTHING.  There are no events that you can point to where you can say "Had we had Trumps extreme vetting, this never would have occurred".  

Most experts agree that the extra step of looking at social media will not only burden visa screeners with more work, but it will cause longer delays in a process that already takes YEARS to go through.
