We cannot be an "Open-Minded Person" but we can be open-minded about ideas. Stigmas often get created because we find ourselves unable to even hear someone that has an idea different than ours. But I challenge people to do research for the things they passionately believe in. Not to change your mind but to strengthen your belief to ensure it's not simply a conditioned response.
We can often shame people into believing what we want them to believe. How many of your beliefs are because you believe them, or you were shamed into believing them? Dive deep and challenge yourself and your beliefs and be open minded to new ideas.
Some articles I post will support my ideas, some may challenge my ideas, I think it's important to be well rounded in thoughts and beliefs so people can come to their own conclusion without confirmation bias. Not everyone has to agree with me, the important thing is we are challenging our own thoughts and beliefs and having these conversations.
