A debate list has very limited effect. Most people that are against BTC are against it because that's what the majority are. Debating won't change their mind because it's a huge social thing. You can prove people wrong all day long as they will just keep coming up with more reasons to be against it until they finally hit "I just don't like it" and end it there.
Giving up the personal explanation because of the majority effect feels like not the right way to treat this subject.
what do you prefer? waiting for a new shops so accept bitcoin?
waiting for big conferences that interest only those who care at the moment?
we need some tool to make the simple person in the street to realize that its not just a nice episode of dreamers. we need more then that.
and by that
we have to explain as good as possible ourselves in any argument on the bitcoin.
