I don't understand why you're being downoted. Didn't even say cats don't belong outdoors, just that they don't belong outdoors unsupervised which a completely true take. For the record, I absolutely love cats which is why mine don't go outside unsupervised. Two of mine have no interest in leaving the comfort of home (one does enjoy the balcony, on a harness for safety of course) and my third enjoys going out on his harness with me when the weather is nice (he has zero tolerance for snow though).

All three are extremely affectionate, loving, and sociable and by all measures happy and content.
