The vegan then goes on to explain how lately it's been getting worse and the community should start researching veganism and become vegans.
"I've noticed a sharp uptick recently in the smell of folks cooking meat and it can be quite overpowering," they write.
"Quite honestly the odour is offensive.
"And I'm hoping our community can have some empathy for its #plantbased neighbours by closing their windows if they are cooking meat and only putting vegetables on their BBQ.
"I don't want to be a stereotype, so I won't go into detail why the odour of cooking animals is offensive.
"But I encourage you to do your research and join the movement of ppl who are fighting back."

"You must be joking. Might I suggest a much simpler solution: don't run at dinner time," one person tweeted.

Others were resentful of the vegan's sense of entitlement or felt it was unfair to expect a neighbour to change their eating habits for one vegan.

Charles Shelfer wondered: "But, how does one cleanse his mind, knowing that 8 out of 10 households along your jogging route are gleefully inside cooking, laughing, and rolling around in, animal meat?"
Many pointed out that the vegan runner was kidding himself when he wrote "I don't want to be a stereotype".
