I agree with this 100%. Suddenly people care about mass deportation, for example, but where were they when Obama was deporting a record 2.5 million people? They are terrified of Trump's "deportation force", not realizing apparently that many such deportation forces (e.g. ICE) already exist.
Some things that the left should have cared about under Obama:
* initiating new undeclared wars
* expanding the surveillance state
* eliminating habeas corpus with the 2012 NDAA
* killing two American citizens extra-judicially
* fracking
* selling arms to radicals and brutal foreign regimes
* the Honduran coup
* CIA black sites / torture (forced rectal 'feeding' to the point of rectal prolapse, for example)
* prosecuting whistleblowers
* raiding legal dispensaries / grow ops and wholesale continuing the ludicrous war on drugs
* pro-corporate policies like the TPP, ACA, and the bailouts
* running up the national debt another 10 trillion or so
* contracting out development of astroturfing software from HBGary / Operation Earnest Voice
I could go on. The real left barely exists anymore in America.
