Let him speak.
No one pushing for this boycott is trying to put a gag on Colbert. Calling for a boycott does not equal silencing speech. Personally, I'd prefer that he boycotts the RSA conference and speaks about it on his show with Cory Doctorow which will get vastly more reach than the RSA conference ever will.
I'm glad there's people asking Colbert to boycott the
NSA RSA conference. The worst that happens is Colbert is made aware of the issues by all these calls for a boycott, shows up anyway and blasts the RSA.
Also, calling for this boycott is already starting to drive discussions all over the Internet and that's a very good thing. To simply beg Colbert to show up to the RSA conference and tear apart the RSA isn't going to cut it, IMO.
Boycotts have a long, successful tradition of helping to peacefully overcome civil rights issues. I'd like to see Colbert help to promote and reinvigorate that imperiled tradition.
If he chooses to show up to the RSA conference and blast them there and/or on his own show, you'll have people like Cory Doctorow to thank who helped bring the issues to his attention in the first place.
Actually, I could even see where Colbert shows up and sarcastically blasts the boycott and then goes on a pseudo pro-RSA rant in the style of his show that shames the RSA. Who knows?
Keep in mind that Boing Boing's Mark Frauenfelder has already been on the Colbert show multiple times. Maybe it's time for Colbert to bring on Cory Doctorow to discuss his dastardly, anti-'merica boycott request of the RSA conference?
In other words, there's plenty more Colbert can do than simply show up to the RSA conference and attack the NSA while leaving the RSA off the hook, and this boycott campaign can get Colbert and us all to do better than that.
If you don't want to support the boycott. At least please try to get Cory Doctorow on the Colbert show to discuss the RSA, etc.
