The emerging trend of people thinking they can just take photos of anyone anywhere for the sole purpose of uploading to the web for groups of people to laugh at

The emerging trend of people thinking they can just take photos of anyone anywhere for the sole purpose of uploading to the web for groups of people to laugh at or make judgement of leaves a pungent aftertaste in my mouth. Sure you might be legally allowed to but it doesn't mean it's not incredibly rude and inappropriate, with total disregard/ignorance of potential consequence like we are witnessing at the moment. I see it on social media sites, people who feel comfortable sitting on a bus and just lifting a camera up to snap someone going about their day who just happens to look different to someone else so everyone can have a laugh at them. Sometimes presented under a thin guise of intelligent wit when actually it's vacuous bullying. Totally oblivious or carefree to the fact the subject matter may have actually noticed them photographing them, I wonder how that makes them feel? This situation feels associated to me. I just don't understand how anyone can be comfortable just snapping a picture of someone to immediately upload on the internet to share with people in a negative way. Are people starting to lose their common sense and decency?
