Publishing in 'leftist' journals or book projects: Impact on career? I am aware that this question is of different relevance for each science field. I am asking as a social scientist/sociologist here. The line between research and own political opinions is more or less clear/diffuse for other fields. 

In short, my field of research is relevant to some more or less intense political discussions, especially coming from the political 'left'. Along with my own political believes (which I don't discuss here), publishing in some journals or book projects is interesting for me a) because it advances my research on specific topics b) it allows me to articulate critique and take a position in public discourse c) advance critical sciences and critique in my field -- and in society as well.

Is it a problem for a pursuit of an academic career, if I publish some papers in 'political biased' journals/books? Of course my own choice of jobs/funding etc. is selective and tends to exclude opportunities that are for example 'too conservative' for me. However, sometimes you cannot chose freely. Further, said publications can be omitted in my publications list; but internet makes one transparent. Has anyone of you made any experience in the either way? Or has anyone expierienced conflicts?
There is nothing wrong with communicating your research to (a part of) the general public. In all likelihood public funding was used to pay for part of your research or used in your university, so it is only fair to give something back when you can. I would not hide it either, that only looks suspicious. Instead I would just add a section to your CV for communications with the general public. It would often be viewed as positive, though other things like publications would be valued much higher. Who knows, maybe you will end up in a very close race some day and that little extra is just enough. 

If those pulbications have nothing to do with your research than those are just your private actions as a citizen. You don't need to mention those in your CV, but I don't think they will be held against you.
