In your case, the vast majority of your comments are highly political, and frankly, unnecessarily emotional. It is far more likely therefore that people are simply reading the comments threads you are in, and downvoting comments as they read them.
I’ve also recently experienced a 100 point drop in total karma, between one night and the next morning, and my comments are not usually nearly that controversial. I have enough karma, and enough experience to get used to occasional downvotes, that it’s not a major source of distress, but I would not be surprised if mass-downvoting is becoming more common.
This doesn’t explain why all of my posts get downvoted at the same time, including posts that are entirely unrelated. A 100 point karma drop where before my posts were contentious but still mostly positive is an anomaly that should not be explained away so easily. Bear in mind that it’s not an either/or thing: people can downvote and upvote my posts for legitimate reasons, which is fine, while others block downvote, which is not fine. You can acknowledge the existence of block downvoting while still disliking my posts, that’s totally ok.
