My four year old son came back from school yesterday very quiet( a bad sign!)and upset.It turns out some of the girls were calling him'f.....g gay' because he likes dancing and singing!!WTF! I told his teacher who said she would have a word with the kids involved as swearing would not be tolerated in his school.Not one mention of the homophobic comments. Is four too young to talk about tolerance? I don't mean a full on discussion about sexuality,but a simple discussion on different people.
