I just want to protect my son

Okay so this is going to be very controversial. I want to elaborate that this isn't about being on a side with the war with Israel and Gaza so plz just don't. My son studied abroad 6 year agos in Israel and fell in love with a guy in Israel and dropped it on me that he's gay and he's staying in Israel. He recently came back, back in September because he and is now husband were trying to decide if they wanted to move to the U.S so they could legally get married. It's completely legal to be LGBT in Israel but gay people can't get married because marriage is religious there. They wanted to legally get married but didn't know if they wanted to move to America so my son and his now husband decided to visit and I got to meet them and it ended with them staying and moving because of everything that happened in Israel. They ended up going to the court house and getting married and they're working on his green card. He's also trying to get a work visa. My son found a job but right now his husband is home and just taking care of my house. I am Jewish btw, but religious wise I'm an atheist. I grew up in a Jewish household and everything. What's going on is my son has this Israeli flag on his Facebook. He had it way before this war broke out. People have reached out to me upset asking if my son is seriously standing with Israel right now. Now my son has stated that he doesn't like war in general because in the end nobody wins and there are innocent people killed on both sides. We have talked about him taking the flag off his Facebook. He doesn't want to because he can say he doesn't agree with everything Israel does but he doesn't agree with America does but he doesn't denounce America and his husband is Israeli and he's not gonna completely denounce apart of him. When they have kids he wants his kids to know about Israel and he doesn't understand how him having a flag out that he's had for a year on his Facebook is picking a side. Now the photo isn't just the flag. Jim and his husband are kissing in front of the flag. It's when they got engaged. I get why he likes it but I think right now to keep both them safe because I know some people who are mad he should take it down. Again this isn't about being on a side. It's about their safety. I have been supportive of my son in law through this because I know it's hard for him. I just want them to be safe. Especially since some people are using this war as an excuse to be antisemitic and regardless of what side you're on we don't have to be antisemitic. Am I wrong for this. I feel bad and he's finally home and I haven't seen him in so many years and I don't want to fight with him.
