Which of the “four freedoms” do you think are most important, and why?

The freedom from fear is, in my opinion, the most important freedom. One should not live their lives in any place afraid. Speech is important, but what if you are too afraid to even speak? Freedom of expression is a basic right, but what if you are too afraid to show yourself for who you really are? Freedom of religion has been allowed for a while in America, but what if you're too scared to express your religion due to oppression? Fear must be suppressed first before we can even think of addressing the other situations. 

Hope this helps with whatever you are doing. Cheers!
