According to current polls, more than 20% are willing to vote for an openly xenophobic, extreme right party of nazi-sympathizers, science deniers and reactionaries. They want to deny basic rights of queers and people with disabilities and call for ceasing to support Ukraine and dropping Russian sanctions. The currently strongest polling party, the center-right CDU, had for a long time been fundamentally opposed to working with the far right, but are now getting more cosy with them, seemingly testing the waters on local and state levels.
So yeah, unless that somehow sounds like a good direction for Germany to move in, “left-leaning” would unfortunately be an optimistic misjudgement of the current state of affairs.
I don’t think anyone was hating originally. The “seriously?” was likely referencing your use of the word, rather than being a comment on the matter of your original question. One can read your comment as being in disbelief that somebody might be unfamiliar with the highly specific acronym you were using, which probably prompted them to comment on the “bubble”.
