Aren't you the one bothered? Everything you just wrote about J1 and CHG is your own speculation. You quite dont seem to apply the same rules to yourself whether it's North or South.
I don't give a darn either way, halfalp, just as it doesn't matter to me other than as a minor point of scientific interest whether the Anatolian languages moved from the steppe down through the Caucasus, or from the Balkans to the Caucasus, or probably less likely, originated in situ. What I do know is that there's no definitive evidence for any of the hypotheses. Plus, it's way too long ago for me to care. If you haven't noticed, I post very little about the whole unending quest for the origin of the "REAL" Indo-Europeans and their langague. Frankly, it's starting to bore me to tears, but when an obviously poorly substantiated claim is made I'm not going to sit here and let newbies or whoever be misled. There's enough false information on the internet.
To repeat, wherever IJ split, I wound up in one area, J in another, and the "R" lineages somewhere else. The population which carried the CHG which wound up on the steppe carried Ydna "J". The massive spread of ancestry from western/southwestern Anatolia and the Caucasus in all directions is incontrovertible. It's also incontrovertible that the difference between CHG and Iran Neo is extremely small. Are you or anyone else going to seriously propose that CHG is NORTHERN because of that small bit of minority ancestry?
That's what I try to do...follow the data as logically as humanly possible, and make reasoned deductions from it. When there's not enough data to come to a firm conclusion, I say so. When the data becomes available, I say so, and if that means admitting I was wrong, I do that too.
If I may blow my own horn a bit, my record so far is quite good, something which can't be claimed for the people whom you prefer to believe, but that's because I FOLLOW THE DATA. For goodness sakes, I've spent the majority of my working life making my living doing that; I'm not going to suddenly change the habits of a lifetime.
What you wrote is completely unsupported speculation which you pulled from the blog of a known Nordicist/Slavicist, whose funding is unknown. Regardless, if data someday is found which supports it, I'll happily change my mind.
I think that about covers it.
I have nothing further to say to you on the subject since you have no data to proffer or papers to cite.
Think what you want; true believers always do, because it's never about evidence and proof; it's about ideology.
