He should.
Nobody, even those of the same ethnic group, want Palestinians in their country.
Nobody.
You have to realize there is a reason for that.
Their fellow race/ethnic group with whom they share the same religion is likely not barring them entry due to racism, but likely due to well founded prejudice.
Why aren't people protesting Egypt, Jordan, Syria, Iran, Saudi Arabia, Yemen, Oman, or Lebanon, for not providing them safe harbor?
I do not believe their reported by Hamas death tolls...they have been saying 30,000+, mostly children since November.
If half your population is under 18 and you are known to use child combatants, you have to expect those armed militants to come under fire and many to die.
You got the right idea, but you are blaming the wrong folks.
Theirs is an enemy within that they must defeat.
