Mine has done that with a lot of pro-cycling/anti-anything-that-isnt-cycling people.
Completely self perpetuated by myself though as I invariable scroll through the comments watching as strangers get annoyed at one another for wanting an excessive amount of cycling infrastructure or none at all.
There was a great one the other day where someone posted a picture of a cycle lane junction where the cyclists had previously cut the corner repeatedly enough to erode the grass away. The council (probably called "clowncil" in there somewhere) had put a little barrier up to protect the grass which was met with criticism because they should have put tarmac down as it was clearly the "desire lane" of cyclists.
