@Pickled-Pawns Ah ok, good ;)
Indeed, I think black should definitely go for an e6-setup to counter white's Bc4. The only lines where white sometimes plays Bc4 in the Sicilian in a sensible manner is when e.g. black plays with ...g6 and the bishop actually serves a purpose on c4, either in the Sicilian Dragon or in some Grand Prix variations. So going for ...g6 instead of ...e6 would only justify white's move.
And as already pointed out before, 2. Bc4 is not a great move, but it's certainly not losing either. One danger for black might be to think that you should "punish" Bc4 and gain an advantage quickly, but Bc4 is not so bad that you can force an advantage with black (at least that's what I'd guess).
So a "calmer" alternative to your early ...d5 lines could be to just play with e6, a6 (threatening b5), develop your pieces, and just make white regret putting the bishop on c4 for a while. The bishop is not doing much on c4 anyway, so white might even voluntarily reposition the bishop later on. Some lines with an early d5 exd5 exd5 allow white to go for exchanges on the e-file and the b5-e8 diagonal - in some lines it might be better to postpone ...d5 a bit.
