But also, people who don't change their opinion when they learn new information (at least when it's something I agree with), that's a red flag too.
Really, the only way to not get a red flag here is to already go into things believing the exact same thing I do, and refusing to ever change that when faced with new data.
Lol no it's not. Refusing to be honest with yourself and admitting that you were wrong about something after learning more about the thing, is a giant red flag.
