There is a lot of politics on HN __since years ago__, or earlier, which i was not here
That inspired me and let me know we're all political, we can not escape from politics
the reason of why some people thought HN is become political only recently is that certain political things they cared about happened recently
just as you said
> there is so much in politics which has to be talked about now
Silence is nothing but another form of political expression
