For me it ranges. Some people are opposed to the covid vaccine mandate, some people don't want it for themselves, some people (I think only one or two) are anti vax types, some have it but don't think others should have to and some think you're evil if you disagree that everyone should have to.

Facebook's problems go beyond what information is available on it.
