Three different questions here:
1. What political beliefs do you stand for? I am going to interpret this as what beliefs have a heavy bearing on who I will vote for / what activism do I actively participate in, etc. I believe in upholding our civil rights and liberties, particularly free speech (against SOPA-style laws, most censorship, and silencing protests), GSRM rights, and pro-choice. Those are the key components of my beliefs and other key points of interest (such as economics) come after.
2. Which political party do you belong to? None. I am registered as an Independent voter.
3. What do you think of the following: “The growing number of newcomers of other countries threaten traditional American customs and values”? I just read a wonderful, older, article, called “The Way We Wish We Were”, which is about the myth of the “traditional” American family (namely that it does not exist and that many generations have nostalgia for the “old” way and feel threatened by “changes”.) I think the idea that traditional America is being threatened is complete bullshit and any fears of immigrants mucking things up is extremely xenophobic.
