Ok, I finally read the teshuva. Sorry, I’m not following the reference to political points.
In all events, what it says is:
1. It’s not assur in tzaar baalei chaim or baal tashchis.
2. If your ikkar kavana is for fun, it’s achzariyus and therefore ill advised.
3. If your ikkar kavana is for fun, it’s assur because it’s a sakana.
4. if your ikkar kavana is for fun, it’s a bad idea because the sakana makes that they are mazkir your avonos in shomayim.
So,
If you hunt in a farm like that dentist dude, then it’s not a sakana so it’s muttar.
