Wow, time to back off the ledge there.

I didn't say anything about "the size of the venue".  You're just making that up.  

And democracy is not defined by the ability of a gang to show up and shout down a Congressperson as a publicity stunt for TV.  You're purposely conflating the respectful and constructive exchange of feedback that USED to take place at town halls with the publicity stunts activist groups have been ruining town halls with lately.  (And yes, that goes back to the Tea Party activists doing it 8 years ago too, which current liberal activists learned from and have taken to another level).

OF COURSE there still needs to be ample opportunity for constituents to provide feedback to their elected representatives.  But that does NOT include hijacking town halls for publicity stunts.  When that starts happening, it's perfectly logical to switch from town halls to other forms of communication/feedback that can't be hijacked.  Democracy is not the right to cause chaos.
