To be clear, you're not going to get definitive answers from anyone on canonical meanings for the tenets because they're open to interpretation. They were written fairly broadly by design to accommodate various worldviews (and likely to be interesting to discuss).

For me, Tenet IV which talks about the freedom of others to offend is not a paradox. You have every right to remove yourself from the company of those who are offending you, but they in turn have the right to be offensive. Now, that is not to say that people who choose to offend are absolved of the consequences of their actions. In our Satanic social circles for example, if people are offensive, they are removed and are free to go be offensive elsewhere. Therefore, the personal choice to offend as a Satanist is one that must be taken deliberately. I see this tenet as a caution against pushing for restrictive free speech in the public square lest we lose our own free speech which may, through no direct intent of our own, offend people like fundamentalist Christians, for example.

Tenet II which is about the struggle for justice has been kicked around a lot in discussions. The other part of the wording that people ponder is the meaning of "prevail". There are obviously various meanings for both of those words. Justice could be moral justice, social justice, legal justice... I've seen some people question if it even means retributive/vigilante justice and I think that's obviously a bridge too far and incompatible with the rest of the tenets, which are meant to be understood holistically. As far as "prevail" goes, I interpret it to be more of a synonym for "guide" or "inspire" than "supercede".
