Fair enough if you think that mate. Some rejoinders though.
1. Do you think criticising someone is only justified if they burn your house down?
2. It's not hatred, it's objective criticism. The critics have nothing against Fellaini personally.
3. He's not a first choice, true, but he's our default option whenever we're chasing a game, so his importance in the squad far exceeds his ability.
4. If you buy match tickets, shirts and other merchandise, or satellite TV subscriptions then yes, you're paying his wages.
5. If you want to back everything the club and manager do, then up to you. I'd say that sort of attitude has been a major factor in our recent decline though.
1 and 2 : Fair enough but the "criticism" is not totally justified, it's not criticism anymore if even after He gives his all and puts in a good or at least, decent performance you still criticize him. He's not totally useless and actually contributes. I'm sure if another player is in Fellaini's position, people will be much more willing to give the player a chance.
3 : He's an option. If the manager thinks Fellaini can be useful and it helps us to win games (which by the way, really did happen) then why not? options are always good. I'd of course criticize the club if He's here as a first team player alongside Matic and Pogba starting every games but no, He is an option.
4 : I do and yes I contribute despite of how small it is compared to the amount of money They use to pay wages. I'm fine with criticism but not hating a person just because "for some reason" I don't like the guy.
5 : I've said it in multiple threads, as long as I think the club is improving, I'm fine. Call my standard low and is a factor of a major decline (even if it's questionable) if you want, that's alright but I still don't think hating on a player just because you don't like his play style (lumping the ball to him so He can score a header or cause havoc in opponent's defence) is fair. If you're doing an alright job at work and get hate from people around you just because you work in a different way (which by the way is still within the rules and actually contributes to something) will be you fine with it?
Critics are good - They are the sources of improvements. I never said We shouldn't criticize Fellaini but He did well in the match against Arsenal (this forum will be quite unbearable had We lost or drew the game) and some people still want him gone and see him as something disgusting. That, my friend, is hatred and not criticism.
