Regarding credibility and bias on the resource Wikipedia.
Its creator himself disowned his brainchild. It has been taken over by outright leftists and practically all of its articles are imbued with their brain-destroying ideology. I say that they cannot be trusted with even a fraction of the truth that sometimes slips into their articles. It is already as stained as a pile of **** stains a cherry that has fallen into it. On natural topics, too, the articles are becoming dubious. Leftists are bringing their destructive norm into real science, too. And now they have announced a consensus in science about "global warming" and "covid pandemic. What the hell kind of consensus in science? Science has been driven by doubt alone for thousands of years. An example is non-Euclidean geometry or Fermat's theorem. In short, the consensus in science is absolute nonsense!
In conclusion, if you need to find any information, don't look it up on Wikipedia and Google. There are many other sources independent of left-wing nazism - Brave.DuckDuckGo and the list goes on. And find some sources there too, with overlapping facts and credible sources. Here's the firewall and that's it.
