fundies at least are doing what they believe is morally right and trying to live a lifestyle that is consistent with that (even though I believe that they are often wrong)
True in some cases, though there are many fundies which exhibit behavior hypocritical to their views (i.e. some have sex/adultery scandals, and Evangelicals have a higher divorce rate than the national average).
As for the thread question, libertarians can be allies on some issues, but seem to focus on the other issues (economic and guns--the one social issue where conservatives want less government). Fundies probably frustrate me more, but libertarian views on some issues are even more extreme.
