While I agree that the behavior was problematic, I personally think a mature apology and acknowledgement that the science is not necessarily on his side would be a sufficient resolution, if it was offered openly and willingly.

Animal welfare is an understandably passionate topic, so I can empathize with a person’s feelings leading them to decide that what they were doing was necessary to protect the animals that they care about. Because the fundamental motive was a positive one, and only the chosen expression of this motive was poor conduct, I think redemption is a potentially viable path forward that may be preferable to harsher consequences. We could see this as an educational and growing opportunity, if we wished, and forgiveness has merits of its own when there is no genuine malice present.

I should probably disclose that I am not a member of that community, so I personally was not impacted by these actions and may be underestimating just how badly people feel about this all. Being myself an active carnivore that has been vegetarian in the past (well, pescatarian tbf) and having experience with both schools of thought though, I do feel like I can appreciate the thought-patterns that led both sides to their chosen actions.
