Not considering all the evidence, but only evidence which supports your view causes this. If you are unwilling/unable to debate the other side of an issue, you haven't looked into it enough.

Personally I think the COVID19 vax is the correct action to take, i have also read at least one of the "anti-vax bibles" to get an idea of their views (I found it mostly misinformation)

You mention you are not a "flat earther", why is that? What made you decide that this "theory" was wrong, yet you support others?

Lets look at an example of serous conversations people have had with me: "Flat earth theory."

OK, do you believe in gravity? Given gravity is uniform, this generally should lead to round objects in space. Do you agree or disagree with this statement?

So they argue about Gravity... and if it is "real"..

Go to the sink, get water, pour it slowly, what shape is formed.. explain in scientific terms why it is round, but the earth is not....(surface tension, minimum surface area). Could this force impact planets as well absent "Gravity"?

What other planet in the universe is "flat" besides the earth?...
