No, it's because your education is western-centric and Islamic invasions took over the east. Eastern Christians have been subjected to genocide at the hands of Muslims for 1300 years.
Edit - really, someone is asking for a citation that the Islamic conquests happened? Next should ask for a citation that the sky is blue...
This is basic world history, like the discovery of the new world, Alexander the Great's conquests or the Roman empire...

And yes, it happened over 1300 years ago, the first decisive battle was the Battle of Yarmuk, year 636 CE.
How can “genocide” apply to a voluntary religious group? And even if it could, the linked wikipedia article doesn’t seem to support your claim, either. Do you have anything else we could review?
Citation needed. Since year 1300 or for 1300 years? The former is closer to the truth than the latter, AFAIK.
Not a lot different from what the Christians did to non believers in the West, really.
the linked article describes military campaigns between state armies, not genocide
