It’s a difficult one, as when I think I know people well enough to be assured that they won’t try to poke my eyes out for shooting Bambi, I will tell people what I do and I explain the need.
The vast majority get it. They might not want to do it themselves, but they understand the need and most will have venison off me.
But……. I would never post on linked in or the like about what I do as I would get a torrent of abuse. Christ, I posted on a thread last week about chicken slaughtering (the article was more based on US operations than UK ones) with my actual experience of having worked in one such place (my experience was broadly positive and the animals were treated humanely, etc) and I got abuse for that!!!
On the basis of that response just imagine if I said that I shoot deer!
IMO, until we feel safe to open up about what we do, we keep it to ourselves and all of the good that comes of managing deer never sees the light of day.
Unfortunately, as with many things in life, no matter what you say, some will think you are the devil incarnate for harming defenceless animals, no matter the reasoning or evidence behind it.
