Don't be so defensive. I think it's not that people here don't care. They just don't have any idea what a Berolina pawn is or that it is used in a variant called Berolina chess.
I had to look it up. Like you said, in Berolina chess, pawns capture straight ahead and move on the diagonals (including 2 spaces on the first move), exactly the opposite of regular chess. Everything else in the game is the same as regular chess.
After thinking about it for a second, these pawns would lose the ability to support each other in a diagonal chain but could possibly form a vertical chain-- to what use it is not clear.
It seems like it would be harder to use these pawns to protect the king but perhaps that isn't necessarily so.
As to which is stronger, a regular pawn or a Berolina pawn, it seems a strange question, since they will never meet in a game.

Some people may not care about this topic, but I've been seeing online the statement that Berolina pawns (or Hoplites if you play Spartan Chess) are more valuable than FIDE pawns.
To give some background for those who don't know, a Berolina pawn moves like a normal pawn captures, and it captures like a normal pawn moves. Knowing this, the Berolina pawn is not limited to one file, as it can traverse the board almost freely (since they can't move backwards, an H pawn can't reach the A file until it promotes, but whatever). The intrinsic value of the piece is therefore commonly cited as being higher than that of a pawn, because its mobility allows it to resist being blocked.
The downside, though, is that the pawn has only one capture square, directly ahead of it. So, white it can't be blocked, it can much more easily be attacked. In your opinion, is this balanced by the movement of the pawn, is it a large downside, or is it inconsequential? In other words, which is better: FIDE, Berolina, or neither?
