Batman and the Indians

My friend Lydia pointed out that the Hub has shown just about all of the Batman episodes, except for a handful--the first guest starring appearance of Vincent Price as the Egghead, a villain not from the comics, but created for the show, and a two-part episode from the Batgirl season with Cliff Robertson returning as Shame and Dina Merrill as his sidekick Calamity Jan. Checking a Batman chatboard, a few posters conjectured that these episodes were nixed because of the comical, and possibly offensive, depictions of Native Americans.

In the Egghead episode, Edward Everett Horton, the narrator from Fractured Fairy Tales, plays Chief Screaming Chicken, the last of a tribe which leases Gotham City to the original settlers for some pelts. In the Shame episodes, a dour Indian named Chief Standing Pat is part of the western villain's gang. Are these characters offensive enough to warrant not showing the episodes? I'm not Native American, so I can't say. But by the same token should we not show episodes of old sitcoms with swishy gay characters like Uncle Arthur on Bewitched or Hispanics with thick accents or Gone with the Wind because of the simplistic depiction of Prissy? Chief Screaming Chicken and Chief Standing Pat are comic figures but so was everyone else on Batman.
