I didn't find any of the quotes that I read, even if they were out of context, remotely offensive. But I can see how someone who makes it a point to be offended by things might deliberately interpret it in a bad way, and convince other people that that is in fact what was meant by it.
For example, you say that you don't know how you'd convince 13 year old girls to be interested in programming. The normal interpretation is, 'Clearly 13 year old girls are very rarely interested in programming, and Paul Graham doesn't know how to change that.' The nasty interpretation is 'Paul Graham thinks that girls are intrinsically incapable of being interested in programming'.
It's easy to be offended by things. It's also obnoxious and often irresponsible.
