My husband thinks that I should not fear walking alone at night

I have a fear of walking alone or going to places like stores at night. My husband thinks I'm exaggerating my feelings, which has made me really angry. Recently, he mentioned to a 45-year-old woman and two men at work that his wife (me, age 29) is too scared to walk alone. They all giggled!

Does anyone else fear walking alone at night? I live in a safe area, but that doesn't change the fact that I am a woman and could be seen as an easy target.
