I heard of various demonstrations and protests in South Korea. I also learned it’s part of their culture to raise their voices and protest on the streets. The usually quite and rather shy and friendly people change their mood when they think they have to be heard. But that’s what i heard. If you have any opinion about it, please let me know in the comments.
However, when i was still in Seoul before the elections, big crowds gathered in different streets and squares to support their political leaders and parties. Although there were different political groups nearby, there was never a feeling of threat or hate. In the opposite, they seemed to be determined, but also peacefully and smiling, taking it as a nice event to be with friends and same minded people.
Myself had no own political opinion, but just wandered trough the crowds and collected some impressions.
