If you can recognize that pigs are too smart to eat, where do you draw the line? I personally went vegan when I saw a video of horrific abuses happening at a dairy farm and realized I couldn't contribute to that in any way, and subsequently began questioning my justification for any animal products I consumed.

Then it became a game of "if I'm not eating this why am I okay eating this".

Some cows are just as smart as some pigs or dogs. And if you begin to examine the moral considerations involved in measuring intelligence to determine if a being deserves to live, for me that was what led to just going full vegan.

They are - and the people making that comment are typically advocating for abstaining eating pigs (or other animals) and would agree that malnourishment or keeping them as a pet when you don't have the space for a full-size pig is wrong.

This is sad ASF, look at how small that enclosure is.
