I have good reason to believe that political party X engages in harmful practice Y more than other political parties. The numbers stack up, it fits into the theories presented in other papers, and so on. Content-wise, I believe there is enough for a paper on the topic.
However, I am concerned about the long-term career potential of this, as this would be my first paper (I'm still an undergraduate student) and there are downsides to appearing as a naive partisan hack. Is such a paper worth pursuing, and if it is, how should I best go about minimizing that potential drawback?
If you'd like your thoughts and opinions to be directly connected to yourself as a person and follow you as a mark of the understanding you hold for others to openly judge based on their own beliefs, then write a paper with your name attached. Then your writing will be associated with you as your own assessment of the situation at the time.
However, if you're willing to sacrifice any benefit (or harm) that may come with the reprecussions of such an action, there are platforms where you can publish "open letters" anonymously such as http://www.opnlttr.com/about
The advantage here is that you can gather your thoughts, assemble them, and make your case without needing to worry that your words will haunt you for ever afterwards and close opportunities that would otherwise be available.
