Okay, then.
I'm an artist, I've spent a lot of my life drawing and painting people and philosophically investigating ideas about 'beauty'.
It's not 'well meaning' to say that everyone is beautiful. It's just factual. The simple and undeniable truth is that 'beauty' is a completely subjective term defined by the observer (in the eye of the observer), cultural standards vary enormously according to place and period, and every body/everybody has their own visual appeal, fascination, unique appearance if one brings the right way of looking to the subject.
It's absurd to say there is one set measure that is 'beautiful'. Standards vary so wildly across culture/time/place that this is very quickly shown to be utterly arbitrary.
I have drawn hundreds of people, which means I have looked at them closely and for extended periods of time. I have never, not ever, not once, not found something in the appearance of any one person that wasn't interesting, rewarding and pleasing to look at. That might be the slope of a shoulder, the tones in hair, an angle, a texture, whatever. I've drawn men, women, children, with all sorts of bodily and facial variations, scars, presentations. A body is a landscape one can lose oneself in, given time, patience and open mindedness. I'm not being rhapsodic or romantic: it's not a groundshattering revelation to say that every body, as an aesthetic object, is interesting.
Of course, others may and do have completely have different opinions on this, but I can say with a degree of certitude that I am not offering it as a platitude, patronisingly, or in a 'well-meaning and inconsidered' way. I say it as a fact I have observed over many years of experience looking at people.
tl;dr - beauty is in the eye of the beholder, 100%.
