Being a DE noob (3 weeks in) and having put a subsequent several hours of research into this, what's the problem? The most realistic argument I've found is that it irritates sensitive skin, and given that it's present in about 90% of the aftershaves I've seen I figure it can't be too bad (if at all). Yet every instructional video I've found has explicitly had a huge NO ALCOHOL stamp on it at some point, yet none have explained why.
Is there any reason beyond personal preference, or is this as unsubstantiated as the ZOMG NOOBS DON'T USE FEATHERS UNTIL YOU GET 2 MONTHS OF EXPERIENCE OR YOU DIIIEEEEEE!!!! (I've been using feathers quite nicely since shave 5 (I shave every morning) and haven't looked back).
