Flat out we are animals. Like it or not we eat meat and its natural for humans to do so.
The problem with videos that portray cruelty to animals is that its often often used as a sounding board to support vegetarianism solely based on its shock value. To me that's misguided if the issue is focused on issues involving abstinence towards meat eating and thusly points out extreme reasons as to why one should not eat meat. That's bogus and as long there are humans there will never be complete abstinence. Never gonna happen.
To address the issues of suffering one needs to quit trying to achieve the "goal" of complete vegetarianism for everybody ad nauseum because its simply unattainable. Additionally, as to the scheme of things, note that humans overall tend to be among the more "merciful" predators in the animal kingdom, and is exemplified by many slaughter houses that are required by law to properly stun prior to slaughter. In that light, Its not the really an issue of vegetarianism here and to whether its good or bad for people to eat meat which needs to be addressed, but rather, is the reduction of undue suffering caused to which I can agree fully with anyone that it is an area that needs to be strictly enforced, and monitored.
Just so that you know, I support vegetarianism and those who practice such by way that it shows a sensitivity towards suffering and holds a hearty respect to those who do so, but in the reality of life vegetarianism is arguably just as cruel and harsh towards animals and other living beings as slaughter can be itself. As an example, I used to farm as a young-un and can first hand tell you what turns up underneath the plow, disc, and planter in the fields and in various machinery used for the processing of grains, corn, and such. There is much to be addressed on both sides of the issue, and neither position eliminates suffering nor will it. Best we can hope for is to be mindful on a personal level, and avoid (boycott) the places and operations that shows an intentional disregard to pain and undue suffering in other living beings. -NM-
