Fair enough.
I might have presupposed that this was your line or argument before. But it sure was mine and that of many others.
I just don't believe in being classless to a 64 year old who has tried his best at my football club. It's not part of the way I personally think. And it's not a question of agreeing on/doing things like that, for me.
And personally, I don't think he has lacked class. He's a proud man that both A) says some silly things and B) says some silly things you sometimes have to say. It's fine by me. I have never really found an issue with his behavior at United. I actually find him mildly likeable. It's possibly because I view the man and the manager as two separate entities. I don't like doing that tedious thing where the guy is failing so now I'm going to micro-analyze everything he says very literally and be overly critical because he is doing badly.
My disdain for Van Gaal isn't about poor results. I'd never dislike someone for simply being woeful at their job.
You mentioned ruthlessness previously,but in my opinion ,there is a line between that and public humiliation of some of his players. If he fell out with them ,and kept that within the dressing room,then fine. But Van Gaal usually goes above and beyond,sometimes even having unnecessary digs at players long after he's even let them go.
His unwarranted narcisism and arrogance is also an annoying trait of his. That is a characteristic of Van Gaal that extended even outside his management career(See his Koeman feud for example)
His patronising attitude towards the fans and general lack of accountability are further traits of his that adds to that perfect cocktail of a very unlikeable man. But thats my opinion of him,and I respect yours.
