Yes this is very much true. You added a great source that I would like to piggy-back off of from what the meaning of this speech meant. It's titled, "Four Freedoms Speech", in to which Roosevelt proposed four fundamental freedoms in which he believed that all people should poses, some being in correlation/familiar with the bill of rights as well as adding some words of his own, which includes, "freedom of speech, freedom of worship, freedom from want, and freedom from fear."
