I can absolutely confirm, as a lifelong Evertonian, that the feeling towards LFC is utterly toxic nowadays
Remember all that guff about 'the friendly derby', 'fans sitting together' and all that? Not for a long, long time. The last vestige of that went for me one Goodison derby in the 80s when I was on the Gwladys Street and somebody was burning a Liverpool flag.
You still get some of them coming out with the old claptrap about 'Oh, I want Everton to win if they're not playing us', but everyone knows that's just them ruffling our hair and telling us we're plucky underdogs. If we get close to winning something the it'll change. Imagine the scenario if we threatened to win the PL before they do. Then you'd see who's really bitter.
My dad used to say that if Liverpool had Jesus Christ and ten of his apostles in the XI he'd still want them to get beaten. When he died a couple of years ago his last wish was that everyone at his funeral, including his Kopite brothers and nephews, had to wear blue. I made it so, I went in an EFC shirt and I told that story about Jesus in the Liverpool team on the altar in the eulogy. He'd have loved it
He always liked City, as did I and a lot of my mates. In the years when we were both crap, in the '70s when I was growing up, it seemed we were both teams who played in blue and lived in the shadow of insufferable and more successful neighbours. I still have a soft spot for Bristol Rovers for the same reason.
They can shove a 'friendly Merseyside rivalry' so far up their arses they could use it for red and blue toothpaste...
