The registry existed under Obama, but it was created in 2002 after 9/11, partially suspended in 2011, and fully suspended last month [0], though it looks like it remains to be seen whether the suspension will be undone.
Thanks for the link. Looks like that program was only indirectly about religion. It provided a list of countries whose citizens were subject to more intense scrutiny. Most of those countries were majority Muslim, thus most people affected by the program were Muslim. There were successful civil rights complaints about this.
Trump, of course, has suggested a much more aggressive and less subtle program that includes an explicit religious test.
NSEERS is not even remotely a Muslim registry. It says if you're from one of five countries or are specifically selected, you have to pass additional scrutiny to enter the US and are subject to additional notification and reporting requirements.
Well it is effectively the same as what Trump wants to implement. So it is as much of a Muslim registery as his plan. (which, as you argue, is not at all)
No it's not. Trump said he wanted to register people based on their religion. NSEERS says if you're from one of five countries or are individually selected, you have to have additional screening. Also NSEERS doesn't even exist anymore.
The statements of candidate Trump suggested a system far broader in scope than NSEERS to cover US citizens. The Kobach plan to reinstate NSEERS (it was halted in 2011) would presumably involve more invasive point of entry procedures for more countries.
Whichever way it is, the real time to stop NSEERS was when it started in 2002. Since that didn't happen, it didn't stop until 2011. So yes, it is a good time to complain about religious profiling when a new administration is planning to institute it.
