I know you were because you couldn't possibly name the ones republicans are allegedly threatening.
1. privacy (e.g. every NSA news story ever)
2. 15th amendment (c.f. voting machine vulnerabilities and reduction of polling places on college campuses and densely populated urban/liberal counties)
3. separation of church and state (e.g. Texas. All of Texas. But specifically, their influence on textbook content standards leads to a disproportionately conservative & anti-scientific bent in many science books, for example.)
4. Repealing the affordable care act
5. denying and stymying efforts to reduce anthropogenic global warming
6. equal treatment under the law for same-sex couples
Obviously some of these are partisan issues and a die-hard republican might not even agree that all of them are rights issues. However, I would argue that the general trend is for republicans' legislation and policy platform to limit rather than safeguard the rights of the average citizen.
I disagree about WWII because of not only the potential of the Nazis, but the Soviets as well. We would have gone into that war regardless of Pearl Harbor for what I think are noble reasons AND self interest.
Oh, if it wasn't clear I do think that WWII counted as a defense of freedoms. Living in a world with anti-equality foes on the other side of both oceans probably would have limited freedoms of Americans.
The (potential) distinction between the nobility of War2 and War1 is what I wanted to get across.
