Islam is not a race, so I have no idea why ethnicities are being mentioned in a thread about ideology. I believe in the United States at least, the religion of convicted criminals is not recorded by law. I suspect it may not even be legal to do so - I think that may be the case with the census. I know that in the United Kingdom (my own country), the proportion of Muslims in prison is more than three times higher than the share of the general population. But it would be wrong to infer anything from that without further exploration.
If I remember, religious extremism is especially common in societies significantly represented by one religion only, rather than the opposite, which you might expect. It seems in such countries, religious persecution is most severe.

There is no ideology that permits the carrying out of acts it forbids.
Islamic dogma not only does not forbid terrorism, it condones and orders it. Consider for example this passage from the key book of Islam: Quran 8:12-13: '(Remember) when your Lord inspired the angels, "Verily, I am with you, so keep firm those who have believed. I will cast terror into the hearts of those who have disbelieved, so strike them over the necks, and smite over all their fingers and toes." This is because they defied and disobeyed Allah and His Messenger. And whoever defies and disobeys Allah and His Messenger, then verily, Allah is Severe in punishment.'
If Muslims refrain from carrying out terrorism despite the dogma of their religion, then that is commendable, but it would be better still if they denounced its terrorist elements if they see terrorism as undesirable.
There are a few notable instances of largely Muslim groups being persecuted worldwide which are certainly worth raising, such as the Chinese government's treatment of the Uyghurs, the Myanmar's treatment of the Rohingya, and the Israeli's government treatment of Palestinians. Also the Syrian government's treatment of its own people, which has resulted in more deaths than all the previously mentioned genocides combined, the Turkish government's treatment of the Kurds etc.
But we should recognize all such incidents regardless of the ideology of the victims. If you don't, then how can insist on other people caring?
Also, criticizing an ideology that wishes me to be killed if I do not submit to Islam and then tortured in the afterlife while its followers laugh does not make me Islamophobic. A phobia is an irrational fear of something. I do not have an irrational fear of Islam.
