I watched it all and I can't even begin to explain how this is worded to manipulate you, one that comes immediately to mind is the oppression of women.
It starts by talking about Britain First. This isn't just a view held by Britain First but now this view has been tainted by a fringe group of racists it becomes much easier to agree with the narrative of the video and dismiss it.
It then says there's no formal requirement of dress, just a question of modesty - True the Burqa was actually a Syrian custom iirc, but it has been widespread adapted by most Islamic countries and plenty of hadith are far more specific than the Quran.
It also conveniently ignores passages which do suggest the oppression of women, such as the testimony of a woman being worth half that of a man.
Based on these lies alone I would absolutely not agree with anything in the video if you are unfamiliar with the subject.
