I think it's sad that people honestly believe what was displayed on this episode was false. It's hard to realize you are endorsing something immoral. Admitting this implies you would need to change your life. We can't have that now can we?
Everything displayed in this episode was true. There's nothing 'PC' about it. Fact is fact. If someone was changed due to this episode, well, then the show was a success.
Denying the truth changes nothing about the reality. You can trash every activist until you are blue in the face. The facts will remain and people will not stop fighting for this.
