Is Islam a violent religion?

Q: I am a non-Muslim trying to understand Islam more. Here are my questions:

1. With Islamophobia rising worldwide, there is a deeply ingrained perception that Islam as a religion is inherently violent. Is Islam violent?

2. Given the rise of groups like ISIS. In your perspective, how can we address Islamophobia in countries where non-Muslims and Muslims coexist?

3. Recently, wife-beating in Islam became a topic of discussion in the media. Do you agree that wife-beating is a good practice?

Q: When explaining the maslah of Khidaab, my teacher said the following (In his own words):

Within Ahnaaf, there is two qowls on whether you can do black khidaab for beauty (zeenat)

1. According to some, it isn't permissable at all, it is haraam.

2. A lot of muftiyaani karaam and people of fataawa have given the fatwah of jawaaz. (This is excluding the situation when an old man has married a young women, because in this situation it is permissibile to do black khidaab, and this is the qowl of nearly all the fuqahaa).

My question is, do the Hanafiyah actually have the second qowl mentioned above? From what I have read on your website and ask imam, black khidaab isn't permissible. He also mentioned that Allahmah Ibnul Qayim has wrote a list of the Sahaabah radiyallahu anhum who would do black khidaab in zaadul ma'aad.
