The artist, Stonetoss, makes a career on catering to homophobia, transphobia, racism, antifeminism, all the nazi shit.
It is very much deliberate. He tends to use nazi dogwhistles to make his comics pass cursory censorship.
Sometimes he makes merely mildly hateful comics, like this. That is also a deliberate attempt to avoid censorship and spread the comics outside the nazi bubble. This is why he rebranded out of his previous comic "Red Panels" which was all nazi all the time and got banned everywhere.
It's a joke about how vegan and cyclist stereotypes have insufferable personalitys. That's all it is in the end of the day. I thought it was quite humourous. So I decided to share it around.
The only vegan people i know are the most lovely, smiling, and funny people. I only know they are vegans because insufferable conservatives are complaining about them being vegans.
Vegans are insufferable to people who support animal abuse in the same way environmentalists are insufferable to climate deniers and people who want to use more fossil fuels
