Agreed, but...
How is "this particular website may be a bad website you can't trust" racist? It's literally a statement about a website, not a person... A quick glance at their feed shows nothing visibly racist (and a few things that look supportive instead.) I can't say "this person is absolutely not racist" without knowing more, but I sure can't say "this person is racist" because they said "we shouldn't trust that website."
In fact, you're the one that went there...
