Personally, it makes me extremely cross when people who I know not to be practicing/ believing individuals get married or christen their children do so in church. In my view and experience, they’re doing it for the advantages it brings and not reciprocating this back to the community/ congregation.
I am of no faith, but will respectfully attend a service for family/ friends. The last christening I went to, I was very disappointed to see the mother retreat to the back and gossip with friends whilst the service with the regular congregation was going on.
This in spades! These people who just use the Church for their convenience and the nice photos, really grind my gears. They are always, without fail, rude and ignorant towards the Church, before AND after their wedding.
Regarding what a pp said earlier, I know not ALL atheists are rude and judgemental individuals, but SOME are. And as a number of posters have said, it's hugely hypocritical to get married in Church when you are an atheist.

And it's every kind of weird to get married in a CHRISTIAN CHURCH, even if it IS partly funded by 'taxpayers...' 🙄
What number on the list of excuses for atheists to get married in a Christian Church is THAT? 
All this said, the OP is quite entitled to get married in Church, as her partner is a believer and she is agnostic.
She isn't atheist, she said she wrote that in error.
