I tend to position the capo so it's just jutting on to the fret, maybe that's why I seem to get away without too much trouble.

Making not using capos some kind of macho thing just strikes me as a bit ...ill-judged. There are some sounds and combinations of sounds that cannot be achieved without a capo. For example chords including open strings (or capo fretted ones) just aren't the same sound as chords where all the strings are fretted. Hammering on and pulling off and bass runs and all that just don't work the same way.

Playing the guitar is about music, not about showing off how strong your fingers are. "Never use a capo" is a bit like telling a trumpet player never to use a mute.
