I don't yell at people. And I also don't think a Meme is similar to yelling at someone...

Perhaps people feel much more attacked than what is the intention of the one who posted the meme. It can't be that we aren't allowed to make jokes or talk about veganism online because people are selectively oversensitive. This meme is really really mild when compared to a lot of the other jokes posted here. Especially when you compare it to the amount of mockery and jokes many vegans and vegetarians have to endure in their personal life.

Meat eaters can't expect to bite all the time but than get all cranky when someone stubs them back.
