You can be an ideologue on any point of the political spectrum. The more important word is pragmatism. If you refuse to acknowledge basic reality despite evidence proving otherwise, you are part of the problem.
For years, people have bashed NAFTA while ignoring the basic evidence that it has been a net positive for the US economy. If you hear TPP and you have a knee jerk reaction because Sanders or Trump told you it's bad, but you can't even describe what it is on the most basic level, you are the bad kind of ideologue.
If you spent 8 years screaming about Obama imposing martial law and FEDERALISM but then look the other way when Trump abuses power, you are the bad kind of ideologue.
If you think Tulsi Gabbard's trip to Syria to meet with a cold blooded killer in Assad and with people like Mufti Hassoun, while bashing Clinton for taking money from Qatar. Guess what, you're a hypocritical ideologue.
It's not that hard people, this isn't college debate class where you can contort yourself into some bullshit gray area. It's just common sense.
