A strong movement has to be willing to not only discuss the issues on which everyone agrees, but also to debate important issues in which opinion isn't settled. The goal isn't to get acclimation on every issue, but to understand the views of allies with differing opinions. By dampening distrust, it allows more robust cooperation on issues where there is agreement.
The conservative movement, in particular, has to be willing to confront important issues, even if it causes some members discomfort. The left comes from a singular philosophy: increase centralized control over citizens. Conservatism is built on the sanctity of the individual, but its members are animated by different issues. Conservatives must address all issues where individual liberty is threatened, and it must allow all voices to be heard. That is the spirit underlying Breitbart News' "Uninvited" session at CPAC on Saturday.
