The closest phobia I can find to 'fear of football fans' is this one:
Fear of mobs or crowds- Demophobia, Enochlophobia or Ochlophobia (Don't know why it has so many names.)
Here are a more few random ones for your delectation:
Flutes- Aulophobia
Female genitalia- Eurotophobia
Friday the 13th- Paraskavedekatriaphobia
Gravity- Barophobia
Lawsuits- Liticaphobia
Odor, personal- Bromidrosiphobia, Bromidrophobia, Osmophobia or Osphresiophobia
Penis, esp erect- Phallophobia
Shellfish- Ostraconophobia
String- Linonophobia
Thinking- Phronemophobia
Ventriloquist's dummy- Automatonophobia
White, the color- Leukophobia
Air- Anemophobia
Beards- Pogonophobia
Bogeyman - Bogyphobia
There are some wierd fuckers around. I imagine it would be relatively easy to live with, say, a fear of bogeymen or string or even ventriloquists dummies but
air and
gravity, fuck me that is a rough deal
