The whole 'toxic' cliche is boring. It applies only to most fans very justified opinion of the club's board. Demonstrations have been entirely fair and conducted properly.
Everton was rocking vs Arsenal because Manager, fans and team were 'aligned' as Dyche phrases it.
Energy from fans, creating and rewarding endeavour and energy on the pitch. I think Everton fans 'get' that and rightly expect it, and show appreciation when it's on display. I hope the fans sense of fairness will be rewarded more often under Dyche, I think it will be.
I've been a fan of Dyche for years and I thought we should have gone for him and not Ancelotti (becuase in what other way has this club represented a European elite since the 80s?). None. So we need a manager that understands our constraints and the risk of wasting money on dross that offers less than a well-organised committed unit. And a manager that cares when it's not working (which I think only Frank did). None of the other kack since Moyes (ignoring Unsy and Ferguson for a moment).
But I've not seen fans slating players.
And all fans have a right to call out the disastrous depths of incompetence this board frequently demonstrates, that's not toxic. That's taking responsibility.
They players seem to be doing that finally - so the board must see it is their time to move on, too.
