“Liking” Social Media Posts of Jews Transgressing Halacha

I like to be generous about giving out “likes” on social media. But I have lots of friends who are non-observing Jews. And they often post pictures of themselves dining at non-kosher restaurants. Even worse, I have seen several of them post pictures of weddings, either of themselves or relatives intermarrying. These people are not rebelling against Jewish law. They just don’t know better and explaining it to them won’t help them understand it either. They don’t perceive they are doing anything wrong. Am I required by Halacha to refrain from “liking” these posts?
