Let's look to see if there's any truth in your statement:
There is 1 remain option and 3 leave options (splitting the leave vote 3 ways - standard dishonest tactics of remoaner pollsters...)
35%, or so, it's fluid, want to remain.
50%, or so, it's fluid, want to leave.
15%, or so, it's fluid, aren't sure.
Once again, a tiny bit of analysis, looking at the question and results, shows that the remoaners are, as ever, in the minority; a very dishonest and vocal minority...
