I just think most of the housemates don't get Gary.

He clearly needs some assistance on some things and care needs to be taken when conversing with him.

They realise there is likely a lot of work involved with interacting with Gary and they simply cannot be bothered.
Hence Dee's cruel comment of 'not being his carer', and George saying he didn't come into the BB house 'to babysit anyone'.

Somewhere in the back of their minds they possibly feel that they should be more tolerant of him but have no wish to put the time in to be so,so the easiest way to cover themselves as to that is to turn it on him.
They have overlooked that evertime he is up for eviction he is one of the very first saved if not likely the first one saved too.

They are,some of them anyway, just a bunch of probably selfish people who have little empathy with anyone who likely needs some time and effort put in as to socialising in the house.
That says far more as to them than it ever will Gary.
