Dear Felix, this is a wonderful and very thoughtful approach. As Tel says, it’s a great way to be welcoming to everyone. I know many people use art as a form of meditation and escapism from difficulties they might be having and this could really help. For example, a soldier who has seen active duty may not want to accidentally come across an image depicting injury. Similarly a woman who has experienced sexual violence may not want to see explicit imagery. The way you have set it up will ensure that artistic freedom is protected whilst also being considerate of the viewer which is of equal importance. Thank you so much for being so thoughtful in your quest to create a welcoming site for everyone.
