Stating that most Palestinian support the Hamas and their actions is a very big accusation, but your have not provided much evidence for that.

I have read some poll results from years ago and don't have deeper knowledge of the topic, just saying one would be to provide real evidence.

And that's only talking about Gaza. Since you said "Palestine" it should be mentioned that Hamas had not been able to dominate in the Westbank so far, so I don't think what you wrote is accurate.
