I don't know, but a pattern I've noticed lately is that posts that can be understood as "soldiers for the progressive side" will often get two or three downvotes pretty quickly, and then get upvoted back to zero over the next few days. (If they are otherwise interesting they typically get lots more upvotes.)
I suspect that pattern is relevant here.
I've noticed similar things. Probably some knee-jerk votes coming from NRX's, or from folks who just hate seeing political comments here. Or both.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
