One thing that's vitally important to remember is that feeling ''weirded out'' is not a form of harm. It is a completely normal part of socializing. It is the feeling of encountering something unfamiliar. In order to be a kind person, you must learn to how to distinguish between "harmful" and "weird." And then you must accept the weird.
if new information contradicts your sense of how the world works, you should not dismiss it out of hand, but fact-check it instead.
if something appeals to your sense of how the world works, it is even more important to vet that information before sharing it, because if it is misinformation then it is the misinformation you are more likely to share.
