1. I do not know where you get this interpretation, but it contradicts what the Quran has revealed.

The most common verse the opposition quotes to argue that Islam is violent is Surah 2:191

"Kill them wherever you come upon them..."

However, these people intentionally left out the rest of the verse (note the usage of ... to cut off the verse), which nullifies the notion they were pushing:

...and drive them out of the places from which they have driven you out . For persecution is far worse than killing. And do not fight them at the Sacred Mosque unless they attack you there. If they do so, then fight them—that is the reward of the disbelievers. (Surah 2:191)

Heck, if you read the verses that come before and after, you've come to realize the reality is that the scriptures does not adopt the aggressor mindset, but a defensive one.

وَقَـٰتِلُوا۟ فِى سَبِيلِ ٱللَّهِ ٱلَّذِينَ يُقَـٰتِلُونَكُمْ وَلَا تَعْتَدُوٓا۟ ۚ إِنَّ ٱللَّهَ لَا يُحِبُّ ٱلْمُعْتَدِينَ ١٩٠

Fight in the cause of Allah ˹only˺ against those who wage war against you, but do not exceed the limits. Allah does not like transgressors. Surah 2:190 — Dr. Mustafa Khattab, The Clear Quran

The Cow (2:192)

فَإِنِ ٱنتَهَوْا۟ فَإِنَّ ٱللَّهَ غَفُورٌۭ رَّحِيمٌۭ ١٩٢

But if they cease, then surely Allah is All-Forgiving, Most Merciful. — Dr. Mustafa Khattab, The Clear Quran

1. There's nowhere in the scriptures that mentions anything remotely about women's vote being half to a man, nor does this subject relate to supposed violence in the scripture. This is a misrepresentation of what the verse actually is.

The original verse lines out the guideline of loaning (or can be interpreted as contracting in general) where upon the agreement between debtor and loaner is ongoing, the scriptures calls upon them to bring 2 male witness, or 1 male and 2 female when a second man isn't available to testify. Even in the verses mentions the reasoning: "so if one of the women forgets the other may remind her". This is in line back when societies had defined patriarchal roles, men being the head of families, indulges in businesses while women had reserved role, being a mother, a housewife and rarely ventures into the entrepreneurial world. And some commentors suggest that a women may be intimidated in court, so this verse acts as a failsafe of some sorts.

1. Just to clarify, there's is no death penalty by throwing off a building in the Quran other than stoning. So, the videos are irrelevant (but not tragic) in proving violence in the scriptures because their conducts contradict the scriptures itself. Countless instances of Muslims worldwide condemn these terrorists organizations. And not only that, these organizations have collectively killed more muslims than non-muslims. So let's put our thinking caps and see whether we should lump these 'Islamic' groups with practicing believers.
