Option 3: I remember I don’t have to take sides?

If you don’t know enough to pick a side, then don’t. If the topic comes up, take that opportunity to learn something.

I just ignore it until either things become clear or it blows over

Look for kindness. Look for a group trying to build something for others, not just tear something down or personal gain.

“Does this have anything to do with me?”

Most cases, the answer is no and I simply have to not care about it.

I don’t typically take sides unless one is very clearly in the wrong or one makes the very regrettable choice of fucking with me after being warned.
