It's long been known for centuries that leftist ideologies are used to create subversion. What you're describing (the right and left both being corrupt) has nothing to do with this post. It's not just the political parties, but the leftist ideologies that are being used to destroy western society. It's literally a form of brainwashing that targets the more emotional, weaker-minded leftist type people. This was described in detail by KGB members 30-40 years ago and it's playing out exactly as they described.

Group identity, oppression narratives, SJW, race war, class war, sex war, men vs women ETC,.. All devices movements that were manufactured by a globalist agenda and directed at leftist, emotionally charged people. once you understand what their plan is, everything becomes as clear as day, and nothing seems random anymore.
