"How is labor history relevant here?"

It isn't relevant here per se. It's a merger with a cousin thread where you did not know what "scab" meant and didn't know about any STEM-related strikes, when I had heard of some, and was quickly able to find several such examples.

"haven't said a word about the shortage"

Do try to read what I wrote rather than what you think I didn't write. In the g'g'parent comment to this one I said that STEM is a meaningless term, and that "the shortage is only in from a much smaller subset of primarily programming related skills." - https://news.ycombinator.com/item?id=11311160 . I explicitly acknowledge that developer shortage is meaningful, even though I reject that STEM shortage is meaningful.

"ad hominem attacks"

Says the person who claims that I do not "have an idea of what good programming skill is".

Says the person who claims that ones_and_zeros is advocating a "very nativist, xenophobic, extremely right-wing and anti-progressive" view.

The Wikipedia entry for 'ad hominem' points out "Ad hominem reasoning is not always fallacious, for example, when it relates to the credibility of statements of fact." Let's go back to your statement "I've never heard of strikes occurring in STEM fields." If you had deep knowledge on the topic then that would be meaningful. If you had shallow knowledge then it carries little weight. In that thread I pointed out your apparent lack of knowledge. Now I pointed out the reason for it. This means I know to attach less weight to future statements you make. My attempt to assess your credibility is one of the non-fallacious uses of ad hominem reasoning.

"lump of labor fallacy"

Interesting. I'm saying that STEM is a meaningless term because it lumps people together too much. Where is the increased financial and political support for evolutionary linguistics, urban anthropology, and palynology, which are all part of the "S" in STEM? Since by my reading, most people at the policy level equate "STEM" fields with the subset of science, technology, engineering and math that helps solve more business-oriented problems.

How you turn that into a belief that I believe in a fixed lump of labor is beyond me.

And what of your professed morality gives you the right to say that I don't "have an idea of what good programming skill is"? What evidence justifies that name calling? Or do you justify it because you have concluded I am the despised Enemy who deserves no better?

It's easy to dress yourself in the clothes of righteousness. The feeling of moral outrage is powerful. But your call to "ich kann nicht anders", used so profoundly by Martin Luther King Jr. while in the Birmingham jail, no more justifies your conclusion than it might justify King's namesakes' 'Von den Juden und ihren Lügen'.

I tell you again I AM AN IMMIGRANT. MY FATHER WAS AN IMMIGRANT. Your shots are clearly wild and disconnected from reality. You appear to believe that anyone who disagrees with you in the slightest is "beyond a shadow of doubt hateful and xenophobic".

Isn't life so clear when you live in a absolutist world of black&white world, and work on the side of Jesus? Too bad for you that that's not the real world. Nor is it world I aspire towards. I don't want to be subject to the whims of people who ignore evidence counter to their conclusions.
