It's alright saying "no thanks, don't fancy that" but realistically, it isn't going to be stopped now unless there is a general election before October, even then Johnson would surely stand a very good chance of landing a big majority, all the more so if he colludes with Farage.
No, I'm afraid the writing is on the wall. Johnson as PM will set the seal on that. The EU know him and will know further negotiations are going to be a waste of time, so any notion of them falling over themselves to offer something better than they did May is a complete non-starter. Parliament can try and block no-deal but it is the default position, any PM who desires that outcome can just run the clock down.
By all means carry on the fight, but I'm afraid the lunatics have taken over the asylum.
It might take some real pain to wake people up to what a no-deal Brexit really means. Warnings are no good, they will continue be batted away as "Project Fear". Real tangible consequences are required. Get it over with. Then it will be time to start talking about rebuilding the country.
Hold on to your hats.
