I gotta go the same route as Avs
I have had POS pax next to me who can buckle belt and put down armrest--but they still have spilled over under the armrest into my space and that is not acceptable for anyone.
The issue of how fast they can get that belt/rest up/open is a HUGE issue (no pun intended about their girth/size) for SAFETY of all pax--if they are blocking ME--I'm going OVER if I have to. They do NOT have additional or special rights--it is not a handicap situation--these people made a choice to be fat (THEY CAN CONTROL THEIR SIZE--sorry I disagree Avs) and they need to deal with the consequences--no one else should have to suffer for their obesity.
I don't apologize for my opinion.
