If Daniel has such extreme views, it’s possible Lucille has milder ignorant views as well. Natasha liking his posts shows they were raised in a house where it’s deemed acceptable. As someone said it may explain why she’s very quiet on topics where she should use her platform for good. If she doesn’t support it, she probs keeps her mouth shut so she doesn’t face backlash. If she doesn’t share the same views this is a great time for her to prove she has a backbone and address it. A simple “my brother has posted offensive things, and I’ve spoken with him and do not share the same views” would earn her a great deal of respect. She can’t stop Daniel, but at least it shows she’s not like him. However, I expect it will be radio silence on the issue.
