Wikipedia is not a proper source and I’ve no idea why people stopped considering this and now use it as such. The graphic may be fine, but provide a real source when pushing back against another commenter.
To be fair to Wikipedia, it’s come on a long way since its early days when anyone could make whatever edits they wanted. The most popular entries on the site are very well vetted, though not perfect. Just my 2 cents.
This place isn't debate club and nobody's getting a prize for winning an Internet argument.
