I think today it translates into every platform due to the highly polarized political landscape. This sorts people into just 2 buckets, after which each bucket is dominated by radicals or semi-radicals. That's why I dislike the term "bubble", because it fails to describe the inner working of the bubble. It suggests that it is uniform and consensus-based, whilst instead they are ran by an autocratic elite that "softly" silence dissent. By making dissent costly. The state of online conversation: 50% of the population is evil. Luckily I'm in the good 50%, which is full of terrible ideas but I can't afford to challenge them.
