Innocent from the perspective of the person who is sharing. They intended no harm, they did not want to get involved in somebody else's agenda.
You clearly view the photograph in a different context, and you see harm. That's fine, but if you're going to bring that context into other people's communities, you have to realize moderators may not want every person to be held to your standards. Hence the banning
Most of the risk comes from the processing and handling of the meat. If the chicken isn't perfectly healthy, and the butcher isn't very careful about keeping the intestinal tract from spreading, bacteria from the intestinal tract could spread to the meat.
This is the same reason that you need to cook ground beef to a much higher temperature than you need to cook a steak, more surface area, more points of possible contamination.
Is it possible to process and eat raw chicken safely? The Japanese certainly think so, it's a dish that's available widely in Japan.
It's up to you, and your risk tolerances. But if you're going to do it, you have to make sure you source the meat cleanly, it's processed very cleanly, it's stored very cleanly. It's a high bar
I don't think this is a Lemmy world issue. I think on many instances you would also see the same behavior. Somebody sharing something genuinely, innocently, and it's being leveraged and twisted into a political moment. That discourages people from sharing.
In your scenario, you would know the health of your chicken, so you could make your own risk calculation.
You would still have to be incredibly careful, and be very clean, when processing the chicken, and when preparing the meal.
I think as with all other raw foods, such as sashimi, it's something to try only if your immune system is working really well.
