Do not worry about him. I read his post and disagree with him. At least for you I do. You are my only Korean friend on Steemit so I can only speak of my experience with you. But your posts are lovely, you are a very kind person, and I love having you here! Ignore his opinion. If he was actually concerned about what he says, he would be flagging the pornography posts on Steemit that make $100 for posting a nude photo without sentences. Those are the posts that take away from Steemit, not the Korean posts. We can actually learn something about different cultures with Koren posts. Also, I hope you know that he is not the real politician Bernie Sanders. He is just someone using that name. I would not want you to think that's the same person and then dislike the real Bernie Sanders. I hope you have a good day. 😀
