There is a huge range of fact and values standpoints in the EV subject. Most of the negativity is a reaction to the viewpoints at far the extremes of left or right. The second negativity is reaction to misuse or ignorance of facts. Ignorance being based in either non-comprehension or by choice.I'm not sure I understand the general negative and or anti-EV comments.
Pretty normal misbehavior when the viewpoints have gotten more political ( or policy presumptive ) than factual in nature. I'm very pro EV (at a factual level), but I get marked as anti-EV sometimes(and the other way), since I'm plenty willing to state the pitfalls (pro or con).
