Islamophobia is an odd word, it makes no sense. A phobia is an abnormal or irrational fear of something. To have, at the very least, concerns over certain aspects of Islam, is neither irrational nor abnormal. Quite the opposite.
It is a useful word for self-righteous, sanctimonious leftie though, they like to use it a lot, a bit like dog-whistle and victim-shaming.
