Quora's community is a great place outside of politics to ask questions and get answers.
However, if you're looking for a variety in political opinion, you should avoid it. There's not much to say past the fact that there's a heavy liberal bias. Anti-GOP, anti-Trump comments get upvotes. Anti-Clinton, anti-Democratic comments get downvoted. Top comments in political questions are always pro-left, anti-right comments. Ask questions that incriminate or scold the left side of the aisle, and get a downplayed, or hostile answer -- not a straight answer. All Trump supporters are bigots, racists, and sexists. The educated supported Clinton. Bernie supporters are spoiled brats. Etc. Etc. Not a friendly place to be if you're a moderate or Conservative. When you ask them why Quora has a liberal bias, expect to get a loaded response that downplays the bias which ironically, exposes the bias.
Rarely will you find those who are actually "Liberal" and not radical leftists. When you do, it's a breath of fresh air, but extremely rare. I wouldn't recommend to those who identify as actually being Liberal either.
