You are only now just seeing that Trump agreeing with something doesn't make it bad by default? It's not Good vs Evil here. Reality is more nuanced. Glen Greenwald, Edward Snowden, and Julian Assange also espouse certain views that match those of Trump, even though they all despise the man. It's not like Trump just went down a check list and picked the "evil" option for every issue. And the left, such as Hillary, didn't go down the list and choose the "good" option for every issue. Both sides have issues for which they have horrible self-serving stances that the other side opposes, and thus you will find people you look up to often agreeing with your "enemy".

Your preconceptions are collapsing.

Well I'm pretty sure that they are against it for different reasons. Government surveillance is something that a paranoid, insecure person like Trump is going to love.

Sadly that seems to be a very bipartisan attitude:

Actually, one might have some (small) hope that Trump is actually libertarian enough to tone the surveillance state down. Not hoping for much though.

No one can detect a joke when it involves Trump...
