There are certain cases where it feels very ridiculous. For example, some authors use "her" to refer to even a group of people generally known to be predominantly male oriented. While it definitely won't be criticized by any feminist group, it really is distracting from narrative point of view because most readers feel it's unnatural. I remember thinking "This guy is clearly talking about dudes, why is he using female pronoun?" I also think it's stupid to have to use female pronoun just to be safe, because this in itself is sexism--it implies that they are afraid of feminists accusing them but not afraid of masculinists (if it even exists). When I say it's annoying I am not saying these people are annoying, I'm saying the reality we live in is annoying. In some non-english cultures they don't have this problem because they have ways to refer to people without being gender specific.
