In theory, I think we ought to be able to be ourselves in public, just like you can now be openly LBGTQ+ in public (at least, you can some places), but I recognise that a functioning society has to balance every individual's freedoms. And it doesn't help that the people you are talking about, are almost never just living their lifestyle in public, or even indulging their ABDL or whatever else kink in public. They're indulging an exhibitionism and humiliation kink in public, people seeing them and either laughing or being disgusted is the point, and if they don't get the reaction they want, they deliberately push it until they do. Which is no longer, people can just ignore you, and is now very much in the realm of non-consensually involving them. And it hurts all of us.
