Or just boycott the crazy medieval delusional ceremony, pointing out there is no god, and the reason they’re there is a dogmatic belief they simply inherited from their parents without using any of the higher critical functions of the brain. Also point out that lightening and thunder isn’t the gods being angry, and that aids isn’t a “gay plague”. Mention in passing its 2011, and we should all have moved on a bit more over the last 1200 years.
Tell them that christianity is the same load of bunkum, wrapped up in a “my crazy belief in a spooky old man in the sky who uses us like his personal trainset is better than yours” cover.
Tell them you dont need crazy books about a guy called Yahweah who wants us to murder our chidren, and that the Jews are wrong as well.
Tell them you dont need books ranging 1200-2000 years old writen and badly translated several times inaccurately from dead languages to know how to be a good neighbour or how to live a good life.
Then leave. For a beer.
