The answer to your question is pretty simple anyway for any Muslim who wants to interpret their religion in a peaceful manner - they contextualise the violent stuff as defensive and based in specific historical circumstances.
The underlined is a legitimate response. Another way to put it is that they lie to themselves.
However, the on-going violence by jihadi groups suggests that there are enough Muslims who read the "violent stuff" as .......wait for it ........ violent stuff. Verse 2:191 says that combating 'fitnah', which it calls worse than killing, is an even greater reason for fighting. Read your Qur'an. Learn.
Muslims don’t actually interpret the Quran the way you personally think they should ....
People who want to deny the explicit commands to hate and to wage war always throw the "interpret" card onto the table as though it's a magic get-out-of-jihad-free card that doesn't even need to be explained. Take verse 9:29 for example, which starts with "Fight those who believe not in Allah."
Who "interprets" it that way? Well, these guys for a start:
Sahih International: Fight those who do not believe in Allah or in the Last Day and who do not consider unlawful what Allah and His Messenger have made unlawful and who do not adopt the religion of truth from those who were given the Scripture - [fight] until they give the jizyah willingly while they are humbled.
Pickthall: Fight against such of those who have been given the Scripture as believe not in Allah
Yusuf Ali: Fight those who believe not in Allah
Shakir: Fight those who do not believe in Allah
Muhammad Sarwar: Fight against those People of the Book who have no faith in God
Mohsin Khan: Fight against those who (1) believe not in Allah
Arberry: Fight those who believe not in God
Oh, and absolutely
EVERYONE here:
Ayah at-Taubah (Repentance) 9:29
If you had said, "Not all Muslims actually obey the Quran", then I would have no issue. But, to disingenuously suggest that verses such as 9:29 can be interpreted, or contextualized differently is an outright falsehood.
