PETA and Tribal Government's Objections

I've got my disagreements with People for the Ethical Treatment of Animals, but I have even greater disagreements with the way Principal Chief Michell Hicks has been handling their objections over the bear pits in Cherokee. While the article done by the Sylva Herald has what could be expected with the retired Price is Right Host Bob Barker making his allegations and statements along with responses from those who own the bear zoos, I found this to be particularly disturbing: "Hicks also said he will ask the tribal council to ban PETA from the reservation since they have spread fliers and other materials without a business license."
I've long argued that the Hicks administration has no respect for the First Amendment rights of tribal members. When he acts in such a manner, he bolsters my point. If a tribal member wants to associate with PETA, that tribal member has every right to do so. I hope that the current Tribal Council has enough sense to oppose such a proposal, and I hope Attorney General Annette Tarnawski, who lives in an area where her First Amendment rights are protected and respected, has enough integrity to step back from such a proposal.
Freedom of expression is guaranteed by the United States Constitution and the Indian Civil Rights Act. For such a ban to happen, tribal government will have gone way too far.
For those who may feel it isn't a big deal since it's PETA and may not like what PETA has to say, remember this quote from Martin Niemöller, a German pastor jailed for opposing Nazi control of the churches: "First they came for the Jews, and I did not speak out because I was not a Jew. Then they came for the Communists, and I did not speak out because I was not a Communist. Then they came for the trade unionists, and I did not speak out because I was not a trade unionist. Then they came for me, and there was no one left to speak out for me."
