Animal haters/abusers. Women haters/abusers.
Able-bodied people who expect disabled people on sticks/walkers to move out of THEIR way.
I'm 60, never married, and I don't like kids - chose never to have any when I was 6 - so all the piddly-minded idiots over the years who accuse me of being selfish for choosing to live my life how I see fit. I refuse to have the title of wife, mum, or gran.
Any type of porn/sexual stuff.
Men who send me direct/private messages on social media with their shitty chat-up lines and fake profiles, expecting me to lower myself to answer!
Religious nuts. I don't mean those who quietly go about their religion, but the brainless bores who desperately try to ram it down my throat, waffling on about sins and hell, when they know I'm an Athiest.
The worldwide obsession with coffee. I absolutely hate it and won't have anything to do with it, including in food.
