"Guttermouth's song Mark's Ark" appears to be a sarcastic and satirical critique of the vegan movement and animal rights activism. The lyrics question why vegans don't keep cows as pets or in their apartments, but instead choose to advocate for animal rights. The song suggests that instead of just eating carrots and doing nothing, vegans should actually make a difference by buying a herd of animals and setting them free. The lyrics also talk about pests like cockroaches, rats, and rabbits, implying that these animals cause trouble and should be dealt with. However, the song suggests that these critters also have rights, and people should resist the urge to harm or kill them. There are references to the low intelligence of cows, the spread of diseases by rats, and rabbits being subjected to animal testing with shampoo. These examples seem to mock the idea that animals deserve the same rights and protections as humans. The song also criticizes the perceived inefficacy of vegan protests, suggesting that they involve writing "lame songs" and marching with insignificant signs. The lyrics mock the idea of making a difference by solely advocating for a plant-based diet. Overall, "Mark's Ark" seems to mock and criticize the vegan movement and animal rights activism by challenging their methods and questioning the logic behind their actions.
