I find it slightly amusing to read this from someone who has a Strange Journey avatar

(sorry, couldn't resist)
In my case silent protagonists are some of the only ways I can stomach through a JRPG. It's why I pretty much limit myself to the MegaTen games in that genre.
I just got so damn tired of all the Lyners, the Capells, the Welkins, the Eins, the Yuris the...um...the...that dude from Luminous Arc. More often than not, an annoying pretty boy leader jrpg protagonist can just turn me off an entire game, even if I'm enjoying the gameplay or some of the other characters. I'd rather just go play a game that I enjoy just as much without hating the lead.
While I wouldn't say I prefer silent protagonists (for example, I was pissed when they made Maya silent in Eternal Punishment just to keep that tradition. She was already a well fleshed out and beloved character) I will say that I will always prefer a silent character over a badly written one.
Like Yu Narukami from P4. Sure, he wasn't anything special as a silent protagonist in P4 or Golden, I preferred him keeping his mouth shut rather than his personality from Arena where he was basically just the cliched good guy leader who just said stuff like "All right, lets go." and "I can do this. With my friends."
So yeah, in my case, most JRPG Protagonists can turn me off of a game.
