I do not think Grandads use of the word rabid is wrong although I think, at times in the whole Brexit saga, it could be said about many, if not all of us. What I do not understand is what has happened to the Liberals; they just don't seem to be very liberal any more.
However, there are so many currents going on at the moment. Each group; Obsessive Remainers, Moderate Remainers, Moderate Leavers and Obsessive Leavers all seem to have other things they are trying to protect.
This means that Liberal Party Obsessive Remainers will not contemplate working in the best interests of remain if they have to work with Jeremy Corbyn as they are equally obsessive about their own rise to power.
You would think that Moderate Remainers and Moderate Leavers could work with each other but again Party Politics get in the way. It does seem - the only positive I can see, that Moderate Remainers and Moderate Leavers will work with Obsessive Remainers at least until they stop a No-Deal Brexit. But after that, it's anyone's guess. I can see that as soon as they managed to get No-Deal Brexit stopped (if they can put enough of their other prejudices aside to do it) the Obsessive Remainers could well start asking all the "how can you" questions of the Moderate Remainers and Moderate Leavers and the Moderate Remainers and Moderate Leavers could well fall out on the grounds of Party Politics (again).
You can see one group is missing here. All the Obsessive Leavers have to do is sit back and wait for the other groups to find some reason why they cannot work together and they are home. One No-Deal Brexit served up on a platter.
