It was not a social stigma in general, what I've tried to describe is more the general attitude, which is reflected by the wide usage of Google Streetview Blocking ability.
Sure there was a Pascal class, and its not like you are physically unable to learn CS if you want to, but the environment does not lend itself to leading kids down that path.
The blocking of Google Streetview and the general objection of tracking enabling technologies has more to do with the Stasi history then a general objection against technology.
Also there isn't any requirement to lead kids especially to IT. You can get good jobs in mostly all thinkable sectors of industry or services in Germany.
What is true is, that IT was more seen as a nerd hobby than a profession until around 1998. But this was true for the most parts of the world apart from a few pockets like Silicon Valley.
And in the year 1990 we already had IT lessons in High School where we programmed in BASIC and Pascal.
I think the social stigma came from the your mother being a single parent. There was a lot of discrimination against them in those times.
