DD1 (3.9) is at nursery and recently she has been opining an lot on how naughty boys are and how she doesn't like them and won't play with them.
She did NOT pick this up at home.
DH and I have been responding by not taking it at seriously, but still tackling it
e.g. what about Patrick (her cousin, my DSis's boy, the child she plays best with in the world) - he's a boy, you like him.
well, I know somebody else who sometimes does bold things, but is really a very good girl (i.e. HER)
poor Daddy, he's a boy (DH does very fake joke crying - she knows he's not really sad)
Should I just ignore it? I'm torn between not wanting to take a 3 year old too seriously and not wanting to confirm her idea that boys are bold and horrible and she shouldn't play with them 
There are more boys than girls in her nursery class, and they have parties that only the boys are invited to, so they are a bit of a tribe. Maybe it's just that the class has kind of split into boys and girls.
The stupidest thing is that there are about 5 or 6 children she talks about at home and 2 of them are boys.
Apparently they are not bold like the other boys 
Actually, just reading this I can see how ridiculous it is. I should just ignore.
Has anyone else experienced this? Where is she getting these ideas? From the nursery teachers?
