Remain haven't blocked anything Phil. May's deal was blocked by Leave (ERG and DUP). Johnson's deal has passed but it needs more scrutiny and the application of amendments if necessary. Remain haven't blocked Johnson's deal, Johnson has.
Perhaps if Leave had negotiated a deal that actually respected the whole of the electorate things would have been different. I'd suggest the slim mandate indicated we should stay in the CU and SM. I'd have accepted that, so would the country, and we could have moved on.
But no, May went straight to a hard Brexit with her red lines, and ever since the ERG have been pushing for an ever harder Brexit, with their preference clearly being no deal. Most the country don't want this. Maybe this is what you need to understand, Phil.
