What facts do we have so far?
There are his claims and those of airline. Looks like you have made a judgement before facts have been corroborated.
My personal experiences help me see how his story is true.
His past has nothing to do with his current allegations.
There's a lengthy Reddit post (with evidence of also being in the flight) and fellow passengers have been interviewed.
By the sounds of it Adam was filming another prank, being a douche about it too. Got caught out and I guess he looked to make most of the situation.
I mean apply some critical thinking. The guy exploits racial tension and islamaphobia for a living with his stupid prank videos. Some of his old tweets that have come to the fore don't paint him in a positive manner either.
He looked to film a prank, got caught out and decided to take advantage of the situation.
I'm annoyed he's trivialised a very real issue. It has happened in the past and it will happen again, future cases are less likely to be taken as serious. It's a shame this punk garnered so much attention for being 'famous' when so many legitimate cases go unnoticed.
Edit - forgot to mention that Adam has used racist terms (in particular a very while term against darker skinned people) in previous videos and has made rape jokes in the past. All round dickhead.
