No I am presenting you with the logical conclusion to your statements.
If there is any act of moving goalposts, it’s being done in said process of putting words in my mouth.
“Having the result of my actions pointed out to me is putting words in my mouth”. Don’t ask questions if you don’t want them answered.
Name a criteria for what we shall consider a good source, and assuming it’s an ideologically unspecific criteria,
Get it thru your dense skull: THERE IS NO SUCH THING AS A PERFECTLY GOOD SOURCE. You need to be critical of ANY source, but the only way you can do that is by PRESENTING IT so it can be studied. THIS IS BASIC SHIT. Have you never learned source critique?
When we speak about “good” and “bad” sources, it’s generally common parlance to describe media that is known to lie or which had a heavy bias - Breitbart, Infowars, Epoch Times, Radio Free Asia, Wikipedia - these are all examples of being “bad”. This is not to say that they cannot present useful information, but you should be extremely wary of taking anything presented by them at face value - again you should be wary of all sources, but even moreso one that has a proven track record of a bias.
A source might be good for one thing and bad for another. You wouldn’t trust the press secretary oval office dismissing accusations of sexual assault made by the same press secretary, but you would probably trust it with statements about wildfires in the US. You wouldn’t trust the Japanese government with statements about it having no connection to the moonies, but you’d probably feel safe in trusting it’s statements about shinto shrines or whatever.
You investigate your references for bias, for lies, for truth, you cross-reference with your other references in order to gather a more complete picture, and when you encounter conflicts you weigh the validity of each reference - In large part here the question of “who to trust” should in part be answered by “who do I know has lied before?”
