I've never really thought of myself in terms of being or not being a flat earther.
I am fascinated by the discussions and the questions that are invoked that challenge conventional ways of thinking.
I haven't investigated things enough to say I am or I am not a flat earther.
My friend @flatearth - something I very much enjoy about his character is his willingness to question and investigate things. His perspective from what I gather is not that he has all the answers or knows everything....but that there is a lot of 'questionable' acceptances that are parroted as truths...And we should have more discussions and investigations about such things. I was sharing with someone an old jfk speech and for whatever reason...his words are popping up now, with regards to secrecy and true democracy. I'll find it for you..it's only a couple min.
Thanks for your question, you encouraged me to think about my own self-definition :)
