This is simply false, at least in the US. A small majority favor banning it. It's not huge, but it's not a "deeply unpopular idea".
Here is a poll showing only 42% of Republicans and 24% of Democrats supporting the ban:

I was a bit wrong in calling it deeply unpopular across party lines, but it's certainly quite unpopular overall, and deeply unpopular among Democrats.
You're lumping "not sure" in with "oppose the ban". You could just as easily lump "not sure" with "support the ban" and conclude that not banning it is deeply unpopular.

If you're trying to argue that a majority favors banning it, then, obviously, all opinions other than "favor banning it" have to be lumped together as "don't favor banning it"
