E6 Pin in Classical Dutch In a classical dutch setup, if white doesn't fianchetto and instead moves bishop c4 then it pins the e6 pawn. I don't really want to go into the stonewall even though that's the recommendation of the engine. Is there any variation or move that can get me out that is NOT the stonewall?

The pin of the e6 pawn doesn't seem important at all in this position.  In fact, it is hard to see what White is trying to accomplish with Bc4.

By "going into Stonewall" I guess you mean .. d5, and that is certainly tempting, seeing as White will have to lose a tempo just to put his Bishop on another not-great square.  For an alternative, consider .. Nc6, getting ready for b6 and Bb7 deploying your light-square Bishop beautifully with action on the central squares d5 and e4.  Also, after .. Nc6 the d5 idea will never work for White due to .. Nxd5! and White's g5 Bishop is hanging.
