Racism exists.

Pigmentism exists.

Anti Semnitism exists .

There is no such thing as Islamophobia...an overwhelming and irrational fear of Islam, a belief system ( I've seen a lot of phobics over the last 50 years, not one case of a phobia related to a religious belief system eg Buddhismphobia , Amishphobia or Christianity phobia).

Muslimphobia, an overwhelming irrational fear of a Muslim would be more logical....but these days, what's so irrational about that?

Miso indicates fear as in misogynist, a hater of women...so Misomuslim or Muslimmisia would indicate a hater of a Muslim.

Misomuslimism certainly exists....many followers of one religion hate the followers of another ( eg Hindus/ Muslims in India).
