Bf won’t be friends with..

So my boyfriends old good friend has been trying to reach out to him and couldn’t get ahold of him so he somehow found me online and told me he really wanted to get in contact with my boyfriend. When I told my bf he said he doesn’t care to contact him because this friend had become a Christian and is pretty religious. My bf is atheist (which is fine I am too) but says he can’t stand religious people. What would you think of your boyfriend if he said that?
