I think politics of identity can make normally good people do and think terrible and hateful things.
“Always remember, others may hate you, but those who hate you don't win unless you hate them, and then you destroy yourself.” - Richard Nixon
II don't consider 'tricky Dicky' Nixon an oracle of wisdom, but it's very true that holding hatred in your heart destroys your soul.
Israel is a country. It isn't possible to hate 'a country'. It would be the people of that country who may be targets for hatred.
I do know that hardline white supremacists hold hatred for Jewish people everywhere, including Jewish Israelis, and thus Israel itself. But they also hold hatred for all non-Aryans, all people of color.
But for many people, Jews and not, it isn't about hatred of people. It's great concern about the actions of the current Israeli government towards the Palestinisn people. It's the dehumanizing of Palestinian people, to the point where ... an Israeli soldier, sniper, knowing he will face no consequences because his government supports such actions ... would consciously scope, aim and fire at the head of a 9 year old Palestinian boy who is just standing in his friend's doorway, involved in no protest, doing nothing but being a kid.
That's simply despicable. And a state (Israel) that supports and encourages that deserves to be sanctioned by the international community.
The boycott, divest and sanction movement against Israel is quite valid, imo, and is certainly not hatred or anti-semitism.
