My experience is similar. I was considered liberal for decades. I voted for Obama twice, then for Hillary and Joe Biden. I canvassed for Bernie and Hillary. Then unknown people/entities pummeled all of us with propaganda/censorship causing most "liberal" people I knew to flip without any explanation and often without any concern for the contradictions based on their former recent positions. Such a bizarre thing to witness. For the most part, I'm not the one who changed.

Colin Wright illustrated it well with this simple cartoon:
