Sure. Of course there are rationing panels for healthcare in the UK that have acted as death panels. It was never out of the realm of the likely that any single payer system would have to do this.I can't believe I'm going to do this (i.e., post in a thread such as this), but lest we not forget "death panels" that were perpetrated by Sarah Palin. I'm not saying that liberals don't do it - both sides are supremely guilty of fearmongering.
I'm sorry, but "not saying that liberals don't do it" isn't even close to doing it justice. The entire Democratic message recently has been extreme fearmongering. From damn near everything about Kavanaugh and Trump to Hillary's latest jem about Republicans destroying everything. It's not even close to a 50/50 split.
