Brit here…
Let’s get it right.
Pigs are not filthy animals. The reputation for being filthy stems from crowded factory farming conditions where they are forced to live in their own waste.
Pigs do not shit where they sleep, nor do they shit in communal areas, they have a designated toilet area.They make their beds, and tidy up. These are intelligent, highly social, and clean animals. In fact if you want to go down that road chickens are filthy.
Pork is considered a high and complete protein source, its relatively cheap, and tastes good.
Get a grip.
Hope that helps.
