Open Source is not influenced by political factors. Influencing factors are almost entirely economical, with the exception being decisions by lawmakers.
I'd rather they kept politics and so-called fights against racism out of Software, because they were never problematic there to begin with.
The terms master and slave for example are only in bad taste because people make them to be.
To channel RMS: The political concern there is Free Software. Open Source isn't a political movement, it's an approach to software development that has similar ideas on software licensing.
Consider that it might have always been politized, but the previous status quo might have been more convenient/pleasant to you (i.e. made it easier for you to ignore problems which affect others).
