I think most people who are at all active, outdoors and in public spaces are in little danger there. I love laughing at obese media like OP is talking about. But like you say,that's circus fat. They're not even really worth hating, for the most part. Not even really people in the way that most would use the term.  It's the "big guy" dadbod types that actually get in my way most days. I mean planet size obese people do show up enough in my life to be an annoyance. But it's not that common. My actual moments of hate filled frustration come from the fatheletes, dadbods, thicc women etc etc etc. They're the ones alive enough to still be out, about and getting in everyone's way as they wheeze and waddle around.
