Make a mental model of which people can understand which things. Understand what topics they are even interested in. Understand how disinterested person reacts and know when to stop, and understand how an interested person react and know when you can share. Ask people if they are interested in what you're saying. Check their attention. Check their understanding. Understand which people simply don't have the mental capacity to understand difficult topics and just avoid discussing it with them. Understand which people are judging topics emotionally and avoid trying to reason with them logically because it's pointless. Don't try to drop everything all at once, understanding is gradual. Repeat. Repeat. Repeat. You might have great mental models of the "world" but lack in mental models of other people. Some rational people have really undeveloped emotional reasoning, because they don't use it for themselves, but still use their own emotional reasoning for understanding other people. You can rationally understand other people even if they are irrational themselves.
