I don't see it that way - I think of it as a linguistic challenge. Every group's thoughts are limited by the language the group adopts. Learning a group's language makes one more prone to think as that group does, but it also allows one to keep those ideas at arm's length. And if an idea is difficult to communicate in a group's language, that doesn't make it deceptive to hold it, especially if one makes good-faith attempts to communicate important ideas using the group's language.

And while it is true that some groups hold language and ideas that are both infectious and dangerous, arms-length exposure to many such ideas is much less likely to result in pathology than close exposure to one. Refusing to learn an enemy tribe's language is an uninformed bet that you lucked into the best tribe by default.
