I have looked at your link though not read it all. It says indigenous people in Canada are against anti-semitism and against using oppression of a people as justification for murder, rape and capturing their oppressors. Most people are against these.
That does not mean settlers in the USA did not ravaged native Americans and feel justified because the natives were savage in their behaviour, and the pioneers felt the native people were both a threat, and in the way. They would certainly have called the native people terrorists if the word had been in common use then.
Hamas are not justified in their murdering, but Israel is no more justified by multiplying killing forty fold and destroying the whole of another people’s hospitals, schools, universities, mosques, journalists, doctors, lecturers - because they are ‘a sovereign state’.
And proxy of Iran though Hamas may be, it does but have the fighter jets and bombs, military bulldozers, tanks and drones and intelligence Israel has thanks to the U.S.
Netanyahu is not likely to be creating more security for Israelis by his methods.
