I would say it depends on who decides which sources are valid or bias.
The factual content and objective nature of reporting is what determines whether a source is reliable and credible. Ethical people recognize these high standards.
I have no doubt you lean toward sources which support your own views.
My views are objective and factual reporting. I avoid biased sources. I have a bit of an advantage over most in that I was in journalism in high school and college and the lessons we were taught is objectivity and ethics. I look for these in reporting.
We are all prone to that. I read sources form both left, right or in between. I am more concerned with getting at the truth than whether I agree completely with the political leanings of the source.
If you are an ethical, honest, and open minded person your bias will be towards reputable and credible sources. The source in the OP is not reputable, and is highly biased. The name of the website is highly biased itself, and no doubt is biased to attract those who have a certain far right Christian set of beliefs. What is their aim, the End Times? It's almost comical that you aren't ashamed to cite it.
I have read plenty at this point to make me question Zelensky’s integrity. So I am watching and waiting to see. Putin is brutal and evil tyrant.
You haven't presented anything to question Zelenskyy's integrity. The question about martial law has been explained as a way to help maintain order during a war. This has occurred by many democratic governments during war. If anything it suggests a high degree of competency on Zelenskyy's part. This is how having a good knowledge base helps assess and understand current affairs.
Interesting, though that they have BOTH been a part of Young Global Leaders program, of the World Economic Forum which has been instrumental in shaping a new world order.
New world order? This sounds like right wing fear nonsense. What the EU and NATO have endeavored to do, and done so successfully, is help establish consistency, stability, and order to avoid war and political conflicts. This has resulted in a fantastic era of peace and economic growth in the world, mostly the West. Cooperation and compromises has led to this. The far right Christians seem eager to be in the End Times. They thought the 9-11 attacks was it. Nope. Now they think the Ukraine invasion is. The rest of the planet wants peace and stability, and to get on with life, not this right wing destruction. Let's note Putin is a far right authoritarian leader who is for the most part a fascist. He wants to act via his own rules, and is doing so from a Christian perspective according to some reports. The danger is if the far right Christian base in America will back Putin, and support this extremism in American politics. No doubt, certain Christians are confused and divided. That has been the long term problem with Christianity, it is a confused religion with many massive political and social and dogmatic divisions.
