I didnt see much about religion from a cursory glance at BBCs interviews after the vote, mostly objections to it lacking what those consider enough safeguards.

The objections were mainly by disability rights campaigners.

it will be used the same way it is in canada, to remove "undesirables"
this can also be seen by the severe cutting of disability benefits
they want to get rid of disabled people and this gives them a convenient way to do it
