People are nuts and I need to rant

I shared a video on my instagram story about the hostages coming home, specifically a video of Isreali paramedics removing the poster of Romi since she is now home. Someone I have not even thought about since high school messaged me saying and I quote " pretty irresponsible of you to distribute propaganda in support of a genocide primarily targeting women and children". I assume it's because the caption of the instagram post talked about how they were held captive by the terrorist group Hamas for 471 days and it was from the instagram page Stand With Us. I am by no means a conservative when it come to political ideology, I would say I am a little to the left of moderate but I am also very pro-israel and very proud to be Jewish. I have disconnected with people who are so delusional that they have since become antisemitic but this person I was not even friends with in high school, we are just Facebook friends as what happens when you are in middle school and become friends with everyone. I just do not understand the reason behind someone going out of their way to make themselves look foolish. My response was to say that sharing a video of paramedics removing a poster because the hostage has returned home is in fact not propaganda but thanks anyways and they have not responded and likely will not but if they do - I will not respond as this person is a nut. All of this to say, how do you deal with it? This is the first time someone has even commented to me about this and I have been sharing pro-israel things since far before the 10/7 act of terror and have always shared items of Jewish relations as I am a proud Jew. It just makes me so mad which I know is their goal but still.
