In this post, the flat-earth poster aryzia says her avatar is a picture of a flat earth.  She insists it's a picture of a flat earth even after having been corrected, so here's how you can fight her error.

1.  Visit her profile here:  http://www.cathinfo.com/catholic.php?a=profile&w=4975

2.  Search for her avatar in Google (in Chrome, right-click and "Search Google for this image").

3.  Google will return "Hildegard of Bingen."  Research Hildegard's views on the shape of the Earth.

4.  You will find she was a globe-earther.  Find a higher resolution of the image.

5.  You will see it's clearly a painting of a globe earth.

6.  PM aryzia that her avatar is a painting of a globe earth and request she change it to something less embarrassing (like maybe a flat earth to coincide with her views).

Thank you, have a great day!
