Most of your coworkers are positive. That's a good thing.
The bad thing I see is you already villify the man as a "junk food eating good old boy with a Napoleon complex." This situation is not about him, it's about you. Someone is getting under your skin and you're letting it happen.
In a nation that stands divided every two years, be glad that most of your coworkers react positively to bike commuting.
That pic would be funny though if it came from a cyclist. Kinda like how Asian people can make Asian jokes.
