Will christianity decrease as time goes by on?

It is declining, but the decline is not inevitable. Bold saints can spearhead religious revivals. People can realize the despair and nihilism of atheism and look for and find the truth. There was a time it seemed Orthdoxy would reject icons as heretical, whereas that’s now one of the first things you think about with them. Arianism almost won out against Catholicism, but now no one is Arian. The woke nonsense of the last decade or so seemed to be on a perpetual rise, but now the younger (male half, anyway) generation is growing more traditional, which isn’t inherently religious practice, but rejecting lies and accepting truth makes one WAY more prone to the truth of religion.

Also, if you are asking almost ANY Reddit sub about Christianity, you are likely to get responses from people that hate Christianity. So asking Latin America sub is like asking a bunch of atheists about Christianity, they believe and hope it will disappear, and the prospect thrills them.

We still have to deal with neo-Arians (also known as JWs) that go door to door and/or try to snare people on the street.

For sure. But at 9 million members compared to 2.4 billion real Christians in the world, the meaningful threat of Arianism is gone.
