Naming no names here, I assure you. Just thinking about the British public in general.
It appears to me that we are, and probably always have been, a disunited country. That can be both good and bad. The good thing is that it ensures different opinions which I think must be a good thing in that we can look at both sides of an argument. The bad thing arises when we really have need to have a united country if we are to protect it.
Arguing, or discussing, can be useful in order to examine all alternatives.
Agreeing and uniting is the best way to help our country, and ourselves, to progress and improve.
I think the important thing is to avoid jumping on what immediately appears to suit our own ideas, but instead to seriously consider not what is best for 'me', but what is best for the country as a whole - which includes 'me'.
Unfortunately, not all people can detach from their own set opinons and take a look at the general situation for ourselves as a whole.
