It hasn't avoided that fate. If you doubt me, go into a thread about US politics and praise Donald Trump and watch as your comments get not just downvoted, but flagged so that they are hidden. This will happen no matter how good your arguments are.

Make no mistake, this site is ideologically polarized just like all the others. The only saving grace is that the vast majority of topics are about tech, not politics, so the polarization is usually hidden.
