Yes, it is a bleaching agent. It's not the same as Domestos, though, as that would be very dangerous if swallowed, and the instructions on peroxide mouthwash were to swill it round the mouth, gargle if necessary (I could never perfect that art) and spit it out, not to swallow it anyway.
Whitening teeth might not be to your taste, but it is no different from staining lips with lipstick or tinting lashes with mascara. You might not be able to stand other people doing that either, but both are commonplace. Not 'must haves', but a normal part of many people's grooming routine. (not mine, incidentally - I am a 'brush hair and hope for the best' type, but can stand the idea that others are different.
