You are definitely not being unreasonable. I live rural myself actually - in a little village.
And although I only live in a little two-bedroom detached cottage, I do know a number of people who actually do live in quite large 3, and 4 bed cottages and bungalows and houses, (and even larger properties.)
One woman does have 4-5 big dogs, German Shepherds actually, and 9 acres of land, and 2 gorgeous rescue ponies. SHE has a bit of a driveway before her gate too, and on the rare occasion I have paused there, her dogs go batshit, and I am like 'yikes! MOVE!' I certainly do not think 'fucking dogs, how dare you bark at me.' I move on pretty swiftly. I haven't done it for ages, but I did stop there a few times when I first moved here as I forgot myself.
The behaviour of this cyclist does sound like the classic 'entitled wanker' behaviour many of them do display. Not all, but many... the lycra-clad c*nts/the MAMILS. Despicable men. Probably don't lift a finger in the house, and are shit in bed.
I met a delightful bunch of cyclists over the weekend actually. 40 or so, mostly 45 to 75, and a mix of women and men, and even half a dozen in their late teens. (May have been children of a few of the cyclists,) so I am not saying cyclists are ALL wankers. But we all know many of them are. Especially the crowds of MAMILS. The group I saw were very likely just a bunch of people, from several local villages who get together in the same manner as a walking group/rambling group.
I doubt the police will do anything @Qantaqa So you have a camera up with no sign. Big deal ... I am pretty sure MOST people don't have fucking SIGN on their private property when they have CCTV. Most of the time you don't need one as you can see the bloody camera!
One property about a mile from me (on the edge of my village,) has 2 cameras, and they film you as you pass, and make a loud squealing noise for about 10 seconds. The footage is on auto-delete after 5 days, so they don't keep the footage with you on, but it's there if they are broken into, so they can see the burglars.
The squealing would drive me mad tbh, but they have been broken into 3 times since early 2022, so have very tight security in now. (The cameras have been there since January this year.) They are on the edge of the village and are very vulnerable. Rural theft is on the rise these days.
Oh and your dogs are absolutely precious.
And also, IGNORE the silly 'you were unreasonable to fucking swear' nonsense! 😆
