Brazilian man Nelson Felippe’s Facebook post featuring this picture has been shared widely. Read his entire comment to find out why people have responded so strongly. He wrote: I'm not prejudiced. I think people should do whatever they want to with their lives. But I think it's absurd that I should be forced to witness a scene like this. What people do in private is their business only, but yes, what they do in public concerns me. And I refuse to see a scene like this and consider it normal. They're challenging social conventions, and that can be dangerous. What if some tragedy strikes, or worse, if someone dies, who's to blame. What would happen to a child who sees this scene every day? Kids will think it's normal to wait for the subway on the yellow line. So don't act like that guy over there. Follow the example of the girls. Stand behind the yellow line, and only cross the line after the train stops and the doors open. GayNZ.com staff - 10th April 2015
