I think the point they are trying to make is that the word is used when it isn't valid. For example, I am an American, If I voice opinions against the policies of the USA as I did when Biden was mandating the Covid vaccine, does that make me "anti American"? Not by my definition which includes the fact that freedom to voice my opinion about US government policies is part of what makes me American. It is in my constitution.
I am also Jewish. My cousins are Jewish and my great grandfather on my mother's side was Jewish. My best friend growing up was Jewish. So if I have family and friends who are Jewish while at the same time I voice opinions against government policies in Israel does that make me an "anti semite"? I don't think so. My heritage tells me that all authority comes from God. I must be subject to God and to the laws of God. However, if someone who claims to be a Jew is not subject to those laws I am required by God to call that out.
