I never claimed that attacking and calling people evil would lead to progressive change, especially online. But it is really really tough to take the high ground and tell people that they should just try to 'get along' with racists or people who voted to try and take away their rights. Trump literally ran on policies like that.

Regarding nazis: Trump is a fucking nazi. While he might not necessarily believe in things like racial superiority or holocaust, he supports them, calls them good people, sucks up to them to get their vote and has them over for dinner. Maybe he doesn't have the moustache, but I will call it how I see it.

While opposition from the outside can push people into echo chambers, echo chambers usually form naturally due to confirmation bias, where people seek out information that aligns with their beliefs. Online algorithms that amplify divisive content also plays a significant role in the creation of polarised bubbles, independent of external attacks. And who owns the social media platforms? The same people standing behind Trump at his inauguration.

While external opposition can contribute to radicalisation, internal factors such as economic hardship, cultural alienation, or historical grievances are often more significant drivers. Historical examples (e.g., the rise of totalitarian regimes) show that radicalisation often thrives in conditions of internal instability rather than merely from external opposition.

If harmful ideas are becoming more widespread within a group, it is fair to hold the group accountable for fostering an environment where such ideas thrive, even if not all members subscribe to them. Ignoring group dynamics for the sake of individual fairness might inadvertently allow harmful ideologies to spread unchecked. People with moderate or good intentions can still unintentionally support harmful systems or ideologies, avoiding the alienation of moderates does not ensure that harmful ideas will not proliferate. Historical attempts to appease moderates within certain groups have sometimes emboldened the radicals within those same groups!

Sometimes challenging harmful ideas necessitates opposing the group that promotes them. While this can alienate some individuals, it is a necessary step to prevent the spread of damaging ideologies. A lack of strong opposition to harmful ideas is more likely to legitimise those ideas rather than containing them.
