Ok you need to know this.
((())) means "Jews". That is the origin of the echoes meme. I'm telling you this so you don't look silly in the future. If you think this is some shill shit you're wrong. Google "echoes Jew"
People here often express concern for how this board looks to outsiders who come here.
When you use ((())) it looks antisemitic even though you don't mean it that way.
