It seems based on this thread that lots of HN people expect tastes (in activities or in foods) to be universal? They're not! Everyone in my family loves fishing; I can tolerate it if I'm spending time with them or if there is boating involved. Yet I'm perfectly happy sitting for hours in the cold woods waiting for a deer to wander into range. It doesn't mean that I'm right or wrong or my brother is right or wrong or whatever...
If you have a strong opinion about eating or not eating fish or meat harvested in one fashion or another, that also is a matter of taste. You and everyone around you will be happier from the moment you accept that.
