Probably never. While the percentage of Christians is declining in the long term, trends change & attitudes change. One of the more annoying assumptions that my fellow atheists sometimes make is that society will naturally follow a constant progression towards atheism, something that I emphatically doubt.
Hard to really project out that far, but non-Catholic Christians should become a minority around 2040.
I think you mean plurality. They're still ahead of the next biggest group by 33%, so minority is unlikely anytime soon.
No I meant minority, like the Canadian Conservative party is a minority party. Sure, it's also a plurality.
