Do you understand the concept of reliable sources?

Multiple studies have found Wikipedia to be just as accurate as any other encyclopedia, especially if an article is more high profile and more closely looked at by multiple people, including experts on the subject.

The standard for encyclopedic evidence citation is WP:Verify:

https://en.wikipedia.org/wiki/Wikipedia:Verifiability

It is not Wikipedia which is a source, but the information presented on it cites sources which must satisfy standards of reliability and verifiability.

You, on the other hand, just cited me a picture from imgur, not a source, full of compression artefacts, like you would see on a picture forwarded on Facebook.

Don't tell me what's helpful, don't tell me what Socialism is or isn't, go to the Wikipedia page, edit it to what you think is "political science" and defend your claims on the talk page, debating experts, and then see if your claims hold any water and are accepted as per academic rigor.

Then come back and tell me what's what.

Downvotes certainly don't determine truth. Epistemology does.
