The same reason the Go 1.9 changelog won't be discussed in political forums, opinions on USA's political landscape surely has a better home on the Internet than here.
Maybe, but maybe we'll lose this civility if we encourage this type of discussions.
Again these same types of arguments I've seen happen back home. People used to say stuff like "oh my god do we have to discuss politics here too??!" End result: the country slid down to authoritarianism and now everyone is fucked, even those who insisted on staying in their own little niche bubbles.
