EU referendum, brexit and the aftermath

Very few people, you being in a small minority, will decide not to vote Labour because of them not opposing 'Brexit'. It's definitely not a situation Corbyn wanted to be in, but there's nothing else he can do than what he's doing. And yes, as there are indications that Labour would win a general election before boundary changes, they want it asap (but again, they won't get it unless something very surprising happens).

I disagree with most of what you say here quite strongly - Labour captured the Remain vote, when it becomes clear that a vote for Labour is a vote for Leave I would expect a collapse in support for Labour, especially amongst the younger voters, who are the ones which have come out in huge volume for Corbyn recently.

Also Brexit is going to have an impact on tax receipts that varies between "bad" and "catastrophic", reforming the country whilst in a bitter recession with no quick route out will make a Labour government a short one.

Finally, if Corbyn thinks he can win a GE whilst backing Leave, against a Tory candidate who is likely to be Remain then he is going to lose his deposit.
