They'll never win any argument based on subjectivity. Accepting referees can make mistakes, or be unsighted, is one thing but VAR should have at least recommended the ref reviewed the incidents.
Their point about the VAR official being a Luton fan is very dubious. How would the FA schedule work if refs, linesmen and officials could only be involved in games which didn't impact the clubs in which they have an interest?

If Clatternburg is behind all this then he has no respect for his fellow referees.

If it is the club / owner I would suggest that Clattenburg tell the club this is not what he signed on for and he is being made to look foolish.

That was the intention but VAR gets involved in offside decisions which are so ridiculously close that there can't be any clear or obvious error.
Even though we benefited when Bamford was adjudged offside when his arm was over an invisible line it was an absurd decision.
In the Everton game the third penalty appeal was both a clear and an obvious error because the ref indicated Young had played the ball when he hadn't.

The "Clear and obvious' does not apply to offside decisions as they are deemed factual based on the lines that are drawn to determine whether a player is offside or onside.
