I think that this is a bit of oversimplification - a quite complex social reality flattened under a simplistic psychological concept ready-made for identity politics ("They hate us, because they envy us, because we are special.") In fact, racism involves several different processes, such as: -status generalization (or attribution of conventional stereotypes to unobserved personal characteristics, such as skin color and intellectual or physical ability); - limited and negative personal experience (e.g. "I do not know many blacks/Poles/Jews, but the few ones I met were aggressive/stupid/greedy, therefore all blacks/Poles/Jews must be aggressive/stupid.greedy."
- actual differences in cultural values and life styles - perceived differences, identity politics and reference groups - competition in zero-sum games (such as jobs or college admissions) - divide and conquer tactics of the ruling class (e.g. portraying affirmative action as a "racial quota" system to stir conflict).
Reducing that gamut of to individual emotions obscures more than explains. The phenomenon of IT programmer fascist attitudes is, imho, a quite different phenomenon than racism, but both share some common traits.
The IT programmer's (or any downwardly mobile profession or occupation) are probably best understood as a form of the "endowment effect" or a perception that what one actually has is worth more than a similar thing that one does not have. For example, the job that I have might appear to me as better than a job I can gain if I change my career. In case of IR programmers, or skilled smoke stack industry labor for that matter, that perception was reinforced by the "new economy" propaganda or popular perceptions of what a good job is. From that point of view, any job change appears as a loss and produces anger.
More importantly, the overall direction of the economy and the position of an occupational group in that economy is probably one of the key factors in adopting different ideologies.
If you start low in an expanding economy (as most of the workers in the 19th century industry did) and you see that your upward mobility is thwarted by institutional obstacles (such as property relations) - it makes sense to adopt an ideology that promotes universal rights (as virtually all left-wing ideologies do) because you have nothing to loose from such rights but your chains, but everything to gain.
If, otoh, you start high in a contracting economy or niche (as many IT programmers do) you see that "your" job and a high social status are being eroded. However, you have nothing to gain from promoting universal rights in that situation, au contraire - you have much to loose (e.g. your privileged position). Therefore you are more likely to adopt a protectionist stance and rationalize that by scapegoating some powerless outsiders (Asians, immigrants, etc.) for taking "your" jobs. The smoke stack industry workers did that (cf. the Japanese import smashing rituals in Detroit) and the IT programmers will most likely follow the same path.
It is not surprising that the downwardly mobile blue collar workers and IT programmers who are joining their ranks are the main supporters of the Repug party and fascist politics in general.
