To fight hate-- stop the hateful rhetoric.

"Islamophobia" is hateful rhetoric, like "racist", "fascist", or "Nazi"-- it's a conversation-ender, designed to silence criticism.

Islam is just an idea, subject to criticism like any other idea.

A 'phobia' is an irrational fear. Because the greatest source of terror in recent history comes from some segment of Islam, some amount of cautionary fear toward Islam is perfectly rational.
