In the years that I played the Dutch (always via 1.d4 f5) against primarily 2000-2300 rated opposition, I met sidelines (without a quick c2-c4) nearly half of the time. Also, about a third of the times that my opponent played c2-c4, they did not continue with a kingside fianchetto.
By popularity, the sidelines I saw most were 2.Nc3, The Staunton Gambit, 3.Bg5, and 2.g4.
At first I worried about the sidelines, but eventually I came to enjoy facing them. Why are we playing the Dutch if we don't want to unbalance the game and play for a win, even with some risk involved? From that point of view, 2.g4 and The Staunton should be encouraged! I admit that I never entirely liked my positions after 2.Nc3, but I never liked White's position that much more, anyway.
Against players in that range (and below), starting with 1...d6 gives me all the psychological edge I need. I know many of them were itching to throw the Staunton, 2.Nc3, etc. at the Dutch.
From an
objective, theoretical perspective, however, allowing all the Anti-Dutch lines is likely a better choice than being forced into the Pirc/Modern complex. But in practice I've had some problems against 2.e4 and 2.Nc3. I especially remember a thematic blitz tournament where 1.d4 f5 was mandatory: As I recall it I won all my White games, where I played into main lines, but lost all my Black games to the Staunton!
I like Williams' and McDonald's choices against the Anti-Dutch lines in their respective Dutch repertoire books. But with one exception: They both recommend 2.Bg5 h6?!? which is hard to trust, and anyway I've long been partial to 2.Bg5 g6 as given by Kindermann (and later by Malaniuk). To be honest, when I play 1.d4 f5 it's often because I'm expecting and hoping for 2.Bg5 (but don't tell my opponents that!).
