The guy put on a good criticism for Ole without insulting him as you were claiming in the OP but then your response was to go on insulting him and any other with similar view with things like irrational, non educated, stupid, half a brain, entitled fans, etc.Irrational and non-football educated fans, yes.
Stupid people see the tip of the iceberg, not the foundation. Any fan with half a brain would see the changes happening under the water. We're in far, far, far better shape than at any other point post-Fergie. We brought in tried and tested managers in the hugely successful Mourinho and Van Gaal, and it was an abortion. We brought in a United man, a man who bleeds the club, and now we are seeing signs of progress as Solskjaer has started to rebuild the broken mess of a foundation he walked into, for the future.
But by all means, slag the man off, and advocate bringing in another Mourinho, Van Gaal, etc. so we can all ride the fecking circus ride again; while they chase immediate success and completely forego the culture, climate, soul and DNA of the club, in an attempt to placate the entitled fans.
It's obviously really your own problem and not anyone else. Internet is definitely not for you if you can't handle the slightest criticism to a manager or hear a different opinion than yours.
