That is a way to refute one person the poossibility to inform itself as soon as one entity try to do propaganda. That's not true, that's higly overestimating the power of fake news in a connected society.
You are arguing on the example but not on the topic itself, your refutation doesn't make sense if someone tells you the earth is flat, another one the earth is a sphere, then you can only listen to the people you prefer ? No it's wrong, it's not about choosing your own truth, it's not about choosing your favourite seller, that is the same as saying a car is good because many people buy it. There are better car according to measurement, there are factual evidence of civilian targeting, of launching a war, on refusing to respect the territorial integrity of Ukraine by the russian federation.
Although you can choose to dismiss factual evidence to preserve the illusion/narrative you decided to choose, it doesn't mean you have to.
Thank you i'm not expert on gay things but i'm pretty sure you can change overtime, like barbarians. I trust you on that though. What i meant is that in order to justify an aggression you prepare a narrative that you will write as history if you win. As you may know the famous " history is written by the winners'" or something like that. Now when you launch an invasion you need your motives to be rationnal and to exalt positive value to write in your history. That's what i meant by not look like a total barbarian. It's a idiomatic expression that may have poorly translated.
It doesn't mean the story is true. That's when you need to censor the press , to control historians , to forbid people to express their opinions and so on. All of which are happening now in russia in order to keep the public opinion in favor of the war that the russian federation launched. As soon as the narrative about the "just" war vanishes, the absurdity of the war would leave room for peace.
