This is an extremely disingenuous perspective on a very complicated matter that has Palestinians as the victims in our modern world. I’d advise anyone that reads your comment to dig further into the history of this region
Edit: and to answer your question on how Israel should treat Palestinians. They should treat them like the human beings they are
before 1967 jews couldnt go to the western wall because jordan didnt allow jews near it
1967 israel won the war, and unilaterally created the status quo by giving control over the mosque to jordan with some other rules, again, self imposed.  
jews didnt go to pray there for decades because rabbi's said not to for religious spiritual off limits reasons
Jews never went, so it wasnt a big deal.  Only in the 2000s did it become a hot button issue.  Jews rarely went, and were allowed inside the mosque.  That changed after with the 2nd intifada.  
THe mosque is built upon the foundation of the first jewish temple, go figure.
the place is like central park new york, its huge, not a lot of people except ramadan, and most people use it to get from one side of the city to the other.  the mosque itself is just one part of it. >

Come on. Dude walked around the Temple Mount for 15 minutes. He didn't even go in the mosque. That's a "provocation" and an international incident? >

If it’s not a big deal then why did he do it in the first place, immediately on taking office? Was he just a curious tourist or maybe trying to make a provocative statement? >

Because Jews shouldn’t be barred from entering that place. >

Palestinians also shouldn’t be treated the way they are by Israel. But here we are >

Palestinians, as a collective, have elevated people who murder civilians to the level of national heroes. 
They have been rejecting peace for nearly 100 years and have positioned themselves as enemies of Israel - how should Israel treat them?
