If you agree with almost everything, would it be worthwhile to find a wording which preserves the good content while ditching the bad form?

I also wonder how much of the annoying part is the speaker, and how much of it is the reluctance of listeners to question themselves.

At least it comes from a place in the heart, and not a rub it in your face, "I'll eat two cows because you aren't having any!", ignorance.

It's tough changing minds in general, especially when the topic entails labeling your past and likely present self a serial animal abuser. Something most vegans went through already and had to overcome.
