All the nuclear vs. global warming stuff is off topic.
Look in here if you want to continue it then.
That is, this difference is, for some range of reasonable opinions, a reason to support Sanders and oppose Clinton.
Eh, of course you should look to differences in the candidate’s positions to choose which one to vote for! That wasn’t my point at all though, which I’ve had to repeat on a few occasions now, my point is that there’s enough similarity amongst their policies for a Sanders supporter to at least grudgingly support Clinton in the general election. The idea that she’s some form of stealth Republican is not supported by her policies, unless she gets elected and doesn’t follow through on any of them (which is not a thing politicians tend to do).
(Which was also the point on gun control – you seem not to have picked up on that.)
I did, it was the last thing in the post you replied to. Same point as above.
