70% of them approve of the Oct 7th attacks even now with the fallout. That means that 70% of them are extremists or support the extremist ideology. You cannot separate the two. They agree with and want this.
It's odd that you'd be surprised that they support Oct 7 at this point.
I would assume that the Oct 7 attacks have become more popular with the people in Gaza given what Israel has done since then. That is the point that many of us have been making the whole time.
You can't bomb extremism out of existence, bombing only makes extremism more popular.
