Not a top ten list, rather 108 pages of quotes. A link to a free pdf book found at one of my frequent haunts.
The Volokh Conspiracy. A group blog, mostly by law professors.
I am not a loiya, so most of the legal posts are lost on me. But, they touch on a range of subjects, often enough that I check in frequently.
Anyway, go grab "Liberty Quotes" published online by Christopher Kalabus. It has many quotes related to 2A issues.
I love books of quotes. I always find them inspiring and thought provoking.
