Your idea that the nation has to 'rub along together' and that it could work is far less realistic than Restore gaining power.
As for what Restore might become, we deal in the now, not what you might think happens. If they become another 'Reform', then we deal with that then.....Personally I view Lowe as genuine and I don't see him betraying the British like all the others. But time will show.
I mean what you are talking about with integration never gets beyond 1 in 3 and that was when the numbers were low. Now we have whole parts of the country colonised with non British....whether they were born here or not, they have no loyalty to this country.....a massive downgrade and massive problem.
What you suggest with 'getting on' has never happened in human history when you have big numbers of highly diverse cultures....You always get conflict, the Jews and Muslims being a rather obvious example.....but hey, hope springs eternal with yourself obviously. It goes completely against natural law.....it only works amongst the rich, because they can isolate or integrate at their leisure, with no loss of resources or threat to them....and if they don't like somewhere they can feck off easily.
Besides Restore being a political party is only one aspect. Its purpose is about connections and being a redoubt and trust centre if....or more likely when the worst happens. I know who will and won't stab me in the back.
You stick with Farage.
