This is a really good point and probably sums up most people's view I think.
The big elephant in the room is that he's no longer the perfect fit, no longer the right man, and it's concerning that if he continues he is doing more harm, more damage, than good. For example, the Dychettes are happy for him to stay as "he'll keep us up" or "we won't go down" but there's 28 games just under 3/4 of the season, it's a terrible waste of a season to continue with this manager and this dross. But hey, if that's how you roll.
For me, the manager like most managers it seems, has an expiry date. Lampard came in and then he went. Silva. Martinez. Even Moyes. Smith. It's not something new that Everton Football Club have to consider sacking a manager, nothing new for a club to move a manager on. Seems like some of you think we daren't sack him as that will open up a portal to another dimension and another galaxy.
