AITA for saying my parents' food tasting tradition is "racist" and now everyone's mad at me?

I am Vietnamese and my husband is White. I grew up in a culturally Vietnamese household in America. My family cooks a lot of Vietnamese food, as you can expect.<br><br>When you eat at a Vietnamese table and someone makes something for you, there's an expectation that you eat it all and finish the whole portion they served you as a sign of gratitude and respect, especially when your elders prepare the food. When you're done with your meal, you are expected to finish the portion that they served you.<br><br>My husband hates this tradition and he'll ask for seconds and then leave almost the entire serving on the table untouched. He doesn't finish his meal often and only eats until he's satisfied, not stuffed.<br><br>I told him repeatedly that this is rude in my culture, but he says "fuck that shit i'm not going to stuff my face just to show respect".<br><br>My parents are very upset that he won't eat everything in front of him and my mum has accused him of "being a picky white boy who doesn't know how to eat properly because he's too lazy to finish his meals". She's also mad that he won't try some of the traditional dishes, like balut.<br><br>I was fed up with my husband not listening to me so I said "you know what fine, if you don't want to try new foods or finish your meals that's your prerogative, but you're being disrespectsful and rude to people who are trying to share their culture with you."<br><br>My husband got angry and said "i'm not going to stuff my face just because you people have some weird food tradition that makes you think i'm being disrespectful if i don't eat everything". I told him "it's not weird, it's just a part of who we are and if you want to be a part of this family then you have to show a little bit of respect".<br><br>He said "Fuck off, i'm not going to stuff my face just to show i'm grateful, that's fucking stupid. Your tradition sucks and it makes no sense that i have to stuff my face just to eat with you people."<br><br>I told him "stop being an asshole, you're deliberately trying to offend people by using the term 'you people' like that."<br><br>He said "your food tradition is stupid and racist, you're the asshole for forcing this shit on me."<br><br>And that's when my dad lost it at him. He told my husband to get the fuck out of his house and not to speak to him or my mum ever again. Then he said "he's your husband, you deal with him."<br><br>AITA?
