Hamas affirms that its conflict is with the Zionist project not with the Jews because of their religion. Hamas does not wage a struggle against the Jews because they are Jewish but wages a struggle against the Zionists who occupy Palestine. Yet, it is the Zionists who constantly identify Judaism and the Jews with their own colonial project and illegal entity. Hamas rejects the persecution of any human being or the undermining of his or her rights on nationalist, religious or sectarian grounds.
Note that Hamas is not the only Palestinian faction, but as the one everyone sees fighting Israel, the other factions, and the people of Gaza support them. When the people of Palestine are no longer fighting for their existence, I have no doubt they will support more secular factions as they did before.
IQ only measures how good you are at taking IQ tests. They recalibrate score every year to maintain the same distribution of scores within a year. (they change what each question is worth so every year 50% of tests get above 100, 40% of tests are between 85 and 100, 40% of tests are between 100 and 115, etc.)
The impact is that they have to make the tests harder every year. If you applied modern standards to 1920, the average score would be ~70.
What makes more sense to you, that 8/10 people today would be considered near-geniuses 100 years ago, or we got much better at taking IQ tests?
