Sometimes one has to overstate one’s case as a rhetorical device to make a point. But that rhetorical device only works when one has a point to make. Any other use of the device is a stupid maneuver, which your comment about the “DemoRats, etc.” amply demonstrated.
If I understand rightly, Canadian tar sands oil is difficult to refine; it’s similar in some ways to Mexican and Venezuelan crudes. The US destination refineries are better able to process the tar sands oil than others are. Also, bbl for bbl, pipelines may be cheaper and safer than rail or truck transport, but pipeline leaks are usually larger and cause more damage.
I wonder if market conditions produce situation where so much US production is exported that Canadian imports are necessary. That is the imbalance between transport/refinery/consumption relationships makes it more profitable to export the US surplus production than to transport, refine and use it domestically.
It’s like an allegorical representation of what happens to the minds of normal people when they become Trump disciples (especially the final scene). Whether Republicans or not, they either become or they whelp MAGATs.
