If you don’t see the issue with “often religious” then nothing I say can change your mind! Religion as a moral compass is horrible! Religious communities are often the most toxic ones!
Funny, I use this same line about the right (at least in reference to politicians) in the US.
Perhaps "more people who claim/pretend to be Christian"? You can hardly call someone Christian if they're not following Jesus; it makes as much as calling someone an atheist just because they call themselves an atheist right before talking about how God exists.
