My friend told me the same phenomenon happens in Brazil's canonical subreddit /r/brasil

I'm told that their mods tolerate left leaning hate speech much more than right leaning counterpart so unaware visitors think current left leaning government is beloved by a great majority and that it has been for years.

But they told me that last election ended very tight, something like 49/51% and I'm told current imminent election is at similar 50/50 split.

Same probably happened with German election.
