Having an opinion someone doesn't agree with doesn't make it invalid. I'm not an instance admin, so I have no say in who gets defederated, but in this community I welcome all opinions, no matter how popular or unpopular they might be.
People from democratic countries might call anything that doesn't agree with their world view a propaganda, yet on the flip side, countries from non-democratic countries might call anything that doesn't agree with their world view a propaganda. If we can't discuss our differences, then we are living in a bubble. If someone is never challenged, how can they refine their own position?
Rhetorical question to think about. Americans are likely to elect self-proclaimed authoritarian in the next election, should everyone defederate from instances that allow their opinions too?
In any case, this is not a place for this discussion. I would suggest making a post in !home.
