No risk, no reward.
Think if Theodore Roosevelt wouldn't have taken political and career risks for what he held dear.
There will be a spin one way or the other depending on what a viewers slant is, and we all have them. A good interviewer can see both sides and report it accordingly. But we all know how frailly thin that trust line can be.
The respect, attitude and passion you have, will hopefully bleed through, no matter the twist . Hope for the best, expect the worst. Knowledge and passion combine for a wicked combination, that can be a source of illumination.
There's little doubt in my mind if it goes sideways, we could be very surprised how it could lead to more of a dialogue and get more people motivated to get involved and move off the armchairs.
Truly hope it goes well, even if it's not immediate or seems like it goes sour. Sometimes a slanted, total attack on you or your platform might appear on the surface as a nightmare, but it could get people who might not be active in the political process agitated enough to get involved.
Good luck with it. Hoping it at minimal, leads to some clarity, cracking open doors even a sliver, for future discussions with opposing views that can lead to a bridge building process. It might not resolve anything, but it could be a small stepping stone to something.
