Much more aggressive than the french??! Is this a Joke???? Most lines of the french are quite bloodthirsty. The Scandinavian is not an aggressive opening. The ideas are simple, get a Caro/Slav structure for 100%. the scandinavian is an attempt at an "Improved Caro-Kann" in order to get a solid structure, the idea of both defences. However, while Scandi is more effective at getting the Caro/Slav structure by basically forcing white into a caro/slav and avoiding advanced variation, you lose tempo's and with that, oppurtunitys for attack, which causes a more defensive game in hopes of a superior endgame where you can use you're 4-3 kingsode majority to your advantage. Not saying anything negative about Scandi, it's just your statement is objectively wrong
The scandinavian GAMBIT, and especially the icelandic gambit ARE aggressive. I played the french in tournament chess for years and the exchange variation leads to a VERY boring and drawish game, precisely why I switched defenses.

1.e4 d5 2.exd5 Nf6! is a perfectly valid opening for Black. 3.d4 Bg4, i once applied 4.f3 here (and lost). Have a look at the game Wang-Damaso (China vs. Portugal), where White soon got checkmated. 4.Nf3 looks more solid to me, giving back the pawn.
