By the way, one of the correct move choices for Black after 3... dxe4 4. fxe4 e5 5. Nf3 is likely 5... Be6.

Pfren wasn't insulting anybody. It's funny how people take great offense to when somebody explains how patently wrong their presentation was. He's trying to help you and clue you in. Instead of arguing from a pride-hurt standpoint, you should take to heart that he knows what he's talking about. Do a little research and post sequences that are not based on blunders, and you'll get less criticism over it.
Anyway, I play the same line as GM Shankland does, and found the game to be quite enjoyable for black. It often comes as a shock to the players I face in blitz, where they soon realize the hope for black not knowing what to do is dashed, and they are left not knowing what to do themselves. I can always tell that moment in blitz because there is this pause as white is scratching his head and thinking "Darn... What do I do now?"
BTW, it doesn't matter if you're not a diamond member. All you do is pay a sub for a month and that is easily fixed. Then you can watch all the vids the site has to offer.
Technicaly, he is NOT insulting anyone. He is sharing his opinion! No need to get offended!

Idk bout that
no matter what your level is, you have no right to patronise a weaker player. It’s not as if you were born an IM.
positions are not easy to play or equalize. plus you can find lots of fun ideas. here's some quick AN I did. and yes i've seen shankland videos but white has other ideas too [and better ones than playing the B to c4], playing against d6, bolstering d4 and developing the bishop to e2 to free the f3 knight.
there's a lot of room for creative potential too, obviously. e.g. playing nh3 to cover f2 and induce black to give up his light squared bishop thus freeing up white's light squares... many possibilities and undiscovered ones too. objectively 3...e6 is probably the most solid but ....de and qb6 and e5 probably yield the best practical results b/c black gets some play if white is more clueless.
