I have seen this type of behavior before though. Just recently on an anti-vaccine group I was told by another member that "my heart was black" because I promoted the "VaxXed" movie, because at the ending just before the credits there is a list of demands and one is to make the 3 individual measles, mumps, and rubella vaccines available again (so that people have a choice since the MMR is extra dangerous.)
So basically, I wasn't anti-vax enough for her. Unless one subscribed to her approach 100% they were killing kids, and she said I was killing kids by promoting a film that in realty was only about fraud at the CDC related to the MMR Vaccine, and is not an anti-vax movie but an anti-fraud movie.
That was extra hard for me to take, because I figured we were on the same side.

My point is, that for SOME PEOPLE, you can agree on 99% of the issues, but the 1% that you disagree on makes you an enemy to them.
I'm not sure what % of the issues noganoo agrees with you on -- maybe it's only 50% or maybe it's 99% -- but it is extra sad to me when a 1% difference is enough to make someone that should be an ally into your enemy.
