Whenever I try to argue with them, they tell me that I’ve been brainwashed by “Western propaganda”.

I would ask “What makes you think so?” and go from there.

Likely the only viable way is to guide them into realizing where their biases come from, or that they’re taking views over without questioning them.

If you seemingly can’t change their opinions or views, and it burdens you, it’s fine to accept different or opposing views. You can either evade those topics completely, and if necessary be vocal and explicit about that, or physically leave [the room] if necessary, or make your opposition clear while also making it clear that you have no interest in discussing it further.

Must be the export into an Excel file that breaks it. By that point, an alternative reader won’t help.

400 not being treated for an illness seems quite different and low count vs preventive vaccination of population.

You can only see posts from people who have the same language setting as you.

That is not correct.

Posts are posted with a language set or with none set. In the language settings, the Lemmy UI (in the official frontend) warns that you should not unselect “undetermined” to not miss content on posts that do not have one set.

For example, on this comment, I select EN. When I post in German, I select German.

It’s not about display language settings. It’s about selected content languages, and the languages (or lack of one being set) on the content.

Communities can limit which languages you can post in.

On my comment, it shows which language it was posted in (/is labeled as).
