I suppose you're right about it being the 'best of both worlds' in that there was neither a mass exodus from Labour for being a party of leave, nor was there a mass exodus from Labour for being a party of remain (as arguably there was in 2019 although this was of course only one factor among many in the defeat).
Either way, Brexit was less of a wedge issue in 2017 than it was in 2019. I don't think the idea that 'it was passionate remainers with nowhere else to go' who contributed to Labour gaining seats in 2017 is a particularly coherent one.
I think 2017 was a weird election -i know people who voted labour as a more direct, brexit related "anti Tory" vote, more so than in 2019, so am sure there was some element of it.
Yeah, don't get me wrong—it was clearly pretty odd terrain. Still, it's the only election since 1997 in which Labour gained seats. There are clearly some lessons to be learned from it.
