I provided information that all the Bell/Comeau papers have not been accepted. They FAILED the refereeing process.
i.e. it is not a recognised result. This is not evidence.
Here is something to do for yourself.
Go to NASA ADS abstract service and search the Tifft papers. Look at the papers that cite them.
In these papers are the ones that refute Tifft's findings.
I'm not your researcher. Do it yourself and present upon here some evidence more recent than the early 1990's.
This you have not done! What you did provide was something you thought sounded good to your preconceived mindset on this issue WITHOUT taking the time to research the topic properly.
You should within 5 minutes have learned that the papers have not been accepted for a peer reviewed journal they were submitted to and that the people in question are not workers in this field and that they used someone elses data and did not pursue a research of their own.
Another thing is that you researched this topic to the extent that you were unfamiliar with the analyses that have been performed. Otherwise you would have known that the fact that it is the fainter galaxy in a pair that shows this effect etc.
Next time, come to the table with more than this.
