Anything about cyclists. I just can't read them as they are so full of vitriol and sweeping generalisations.
And then the minute a person with a bike says "hang on a sec, not all of us are utter cunts", they are subject to a mass kicking for not accepting some are and how they can't ever hear a word said against them and here they come being all defensive etc.
And EVERY person who hates "cyclists" will have a personal direct experience of being seriously maimed by a maniac going 100mph on a blind bend at night time with no lights in ninja clothing who deliberately aimed for them, while the poor beleaguered person was helping their blind grandmother back home from the last time they were mown down and nearly killed by a cycling menace.
