In such a situation where information is limited the best course to take is that no opinion exists at all. Remember there is a greatly propagandandized fiction that politics don't matter, that's not even factoring in folks who for example are too overworked to care and other such similar factors. That's not even getting into various forms of voter suppression.

I'd say that at worst it's what may be considered civil negligence, but being pro something assumes intent or active participation. If I don't stop someone from doing a mass shooting simply because I didn't notice them because I'm tired or focused on other things does that make me assistant to the shooting?

Remember knowledge is power both in its acquisition and it's suppression, there's a lot of folks with lots of money enabling the suppression of knowledge. Not in a UFO conspiracy theory way but in a knowing you are being fucked over by politicians and not circumstances sort of way.
