They are and as I've said many times before, they use VAR & "clear and obvious" to justify every decision being correct. One week they'll argue a foul is a foul and it was the correct call to overturn a decision and the next they'll claim the same incident wasn't clearly wrong enough to overturn it. But this is a direct consequence of the abuse. In the same way people feel it's acceptable to say the most horrific things to others on twitter, football supporters are guilty of saying ridiculous **** about officials and this is why they're so defensive.
I can't remember if it was him or another official but I think it was Howard Webb that was asked about officials giving interviews after the game and while some were happy to, others weren't because they were worried about the abuse they would end up getting. Some idiot interviewer for Sky or BT would be so desperate for a big story that they'd look to trip them up and or turn the interview into a witch-hunt.
We all have to grow up. Officials are human and just like players that miss open goals or easy passes, officials will make mistakes too but like it or not, these are the best officials we currently have and until our attitude changes then we won't see things improve.
