You're not wrong, at least in the USA - but it really shouldn't be. The polarisation was ginned up for various bad reasons, including political gain. It's deadly culture war nonsense.

"Polarizing" is a word that kind of applies, especially if one is trying to be polite, but really it's one of the most politically disinformed issues in a long long time.

A bunch of grifters pushed fear, uncertainty, and doubt for personal gain, at the expense of the health of the nation. I try not to blame people who got tricked, but at some point we need to treat people like adults who are responsible for their own actions, and hold them accountable for the harm they perpetuate by believing BS and acting on it.

A democracy cannot function when its members are low-functioning, and when bad information dominates. Those who spread disinformation, relish the conspiracy and disinformation because it makes them feel special emotionally, and wallow in the mess of it, are hurting us all.

I don't recall it being as polarizing outside of the US, where there was a larger group of anti-vaxxers to begin with. But that might be my "outside US" bubble.
