As I said, her discussions on politics show that it's false. Specifically, she states that a group has the right to break away from a nation in order to form a society that is more free than the nation it split from (I think it's in her essay Global Balkanization). This establishes the use of force against people who are violating the rights of others (remember, from Rand's perspective a nation cannot have rights forbidden to the individual). It therefore follows that you have the right to stop a child abuser, specifically because the abuser violated the rights of that child. You are not necessarily obligated to do so, but you are not forbidden to do so by O'ist philosophy either.

Can you provide links please to where she expounded on this? (Remember we are discussing Ayn Rand and what she said - not what others either when she was alive or later on have said about "objectivism".)
Plus of course if you have accurately summarised her views what you are saying is that when her ideology failed to come up with the right answer (right being defined as her opinion as to what was right) she was happy to introduce contradictions into her ideology.
Please go back and read the Nancy Kress link I provided as you seem to have misunderstood what she was saying - her point was that if you follow through on her (Rand) ideas you have to conclude that as an individual I have no obligation, no right to do anything for anyone else, even if their rights are being abused by someone else, and in fact interfering in such a manner is "immoral".
