I sort of get this, actually, and I, for one, would not expect you to feel otherwise!
As stated before, I was married to a Palestinian man for more than a decade, and I remain in regular touch and have even visited my ex-in-laws, especially my BILs and one of XHs cousins, whom I consider a close friend.
As also previously stated somewhere on another thread, I accidentally ended up living through an IDF invasion when travelling to meet my future in-laws for the first time.
Not only was this terrifying, but also: I was deeply traumatised and, as a result, just deeply hated, yes, literally HATED Israelis for a while after this! The way they appeared to be at that time, I just saw them as murderous monsters who would invade towns and villages with their tanks, with their guns, to terrorise and kill innocent people!
... and then, several things happened. I could write some sort of a navel-gazing memoir on the subject of "how a lot of reading, the courage of Israeli activists, and an accident of employment history taught me to actually really quite appreciate Israelis in general and love some as true friends - while continuing to vehemently oppose the political aims of their successive governments". Maybe I will after I retire or something. Probably I will not - the world really does not need yet another "important matters and me, me, me!" book!
But, long story short: I get why you feel this way and - having been there, albeit on the "other" side: in some sense, I think this is valid! You are shocked, and traumatised and you love your family!
Just try to maybe ... eventually ... make sure this does not lead you towards de-humanising a whole people! Maybe learn, hopefully meet, some of them.
It does not have to be today!
