Some people have reached a point where not even disagreeing with them, but simply mentioning someone they don't like in a positive light or mentioning someone they do like in a negative light, no matter how factual the statement is, will get you downvoted.
They can't even articulate it, hence why you didn't get any responses - they just got used to being in their echo chamber where their opinions are always echoed and fervently applauded. After a while, whatever the echo chamber promulgates becomes that person's ground reality. As soon as they see something that disagrees with this reality - it is an offense to them and their whole worldivew, but they can't argue for their beholden view or against the offending view, so they have an emotional outburst.
I've met a few people who proclaimed themselves to be very politically educated individuals, but as soon as it came to a debate they'd get frustrated by failing to answer basic questions about their opinions and excuse themselves. No wonder, who wants their whole paradigm to be crashed in one evening?
