When I originally made that meme, it was just something that popped into my head after seeing a video of vegan protesters going on about the right to life chicken eggs had, even unfertilized ones. They were murdered /potential/ lives.
Vegans are generally "liberal", but given how pedantic some lefties here can be, I knew I had to include the qualifier.
Even Octavia Medley posted an agreement, using an MLP version of the "you have a point" meme, though his response has since been deleted. And I'm pretty sure he does that automatically with all posts over a certain age.
