I’ll spell it out for you: it comes across as condescending. Long-term, especially if you do this in real life too, that means people are less likely to listen to what you have to say, and makes you less effective at tasks that require other people’s cooperation.

Systemically, you might be thinking too much about rationalism, and feeling superior, and not enough about how your choices make other people feel. Feelings aren’t rational; in fact, studies of the brain show that feelings come first and the rational explanation comes later. The only way to elicit a rational response from people is to talk in a way that makes them feel interested in what you have to say, at that comes from how you say it as much as what you say.
