No, I get it - abuse isn't on, you aren't a supporter if you do as you aren't supporting etc. etc.
But while it's a nice sentiment, I think it's a hop, skip and a jump away from saying any criticism means you aren't a 'supporter'. I think you can 'support' by expecting a certain standard and criticising when they don't make it.
The reason I disagree is because of the above. Where do you draw the line? He uses the example of "<player> is sh*t". Sorry, but that's not abuse - that's an opinion. I think Sigurdsson and Davies have been absolutely sh*t for a long time. I'm not interested in supporting them being sh*t. It's up to them to make the grade. I'm not a mindless cheerleader.
That's what I mean about expecting a standard - that's the purpose and the answer to his question. Do I expect Everton to win every game? No, obviously not - but I expect them to compete at the comparative level they should compete at. If they don't, I can't switch my brain off and happy clap because some millionaires might read a tweet and get their ickle feelings hurt.
No, I fundamentally disagree with the premise of it. Abuse, sure - racial, personal attacks, threats, not on. But criticism, of any kind - no, absolutely not. The article doesn't do enough to separate the two.
