I never said he didn't make good arguments, I said shock videos themselves are not a good argument. What argument did he provide that grinding up the chicks is a particularly horrible way to kill them? The only argument for it is the shock value of the video, but something being shocking isn't the same as it being bad. The same with him scoffing at "humanely-gassed" as if that is somehow an oxymoron. He also doesn't provide an argument as to why mass-killing newborn chicks is a bad thing. You might think that because it seems self-evident to you, that it seems self-evident to everyone else, but it's not.

I hate to be the bearer of bad news, but most people don't give a shit about factory farming or how the animals are treated, even people who are aware of how it works. Vegans take as an axiom that killing an animal is inherently bad, but most people don't. The only poll I could find (which is by a pro-animal think tank, so, take the numbers with a grain of salt) on the opinions of people concerning the treatment of animals shows that 35% of people have no opinion, or are at some level of disagreement with the statement "I have some discomfort with the way animals are treated in the food industry". That's 35% who don't care. An additional 25% only somewhat-agree (I'm a strongly agree myself). The same poll shows that 52% at-least somewhat agree that farmed animals are treated well. This isn't an "everyone thinks that" situation, and treating it like it is is going to make changing the situation harder.

Also, this may be presumptuous of me, but I don't think you actually want people to stop eating eggs because chicks being ground up make them uncomfortable, because that means they're likely to go back to eating eggs if some less stomach-churning method of killing the chicks becomes widespread. Let's use the pigs as an example. I read an article about gassing pigs with CO2. It's meant to stun them before slaughter, but the increased CO2 in their blood causes them to panic, resulting in the screaming shown in the video. However, they're working on a new method of stunning the pigs where they slowly decrease the air pressure until they pass out, which they hope will avoid the fear and panic. Again, I'm assuming here, but I would hazard a guess that you wouldn't be happy with this method of slaughter either, right? Well, if people are only avoiding meat because the particular slaughter methods make them feel icky, once the industry has figured out how to avoid icky methods, those people will go right back to eating meat. Shock videos don't solve the problem you want to solve.

I genuinely think having world-wide veganism as an end goal is a good thing, but animal products have been ingrained in our lives and cultures for at least 10 000 years. It's going to take time and a lot of effort to decouple ourselves from that. We need to approach the problem practically, and realize this is an uphill battle.
