Why would you think that? Has it come as a surprise to you to learn that farmers are not one homogenous group with a single viewpoint? Of course they aren't. They're people like the rest of the population who have different opinions and life experiences which influence their thinking.
Or perhaps it has come as a surprise to you to learn that people outside farming make friends and have relationships with people who work in farming. I've lived in this village for the best part of 50 years. My FIL was a farmhand on a local farm, DH was brought up in a tied cottage on the farm - and I wasn't even counting them amongst the farmers I referred to in my previous post.
The two tenant farmers I know voted remain. One of them has a son who has had to go through the rigmarole of getting German citizenship to remain living and working in Berlin after Brexit. They are both family friends.
My brother's in-laws are landowners. They farmed the land themselves back in the day, but now lease their farmland to a tenant farmer (not one of the ones I'm friends with - no idea what their opinions on Brexit were/are). They no longer actively farm themselves, save keeping a couple of horses, and now dabble in the antiques book market instead. They were very vociferous leave campaigners.
It's a little ignorant to think I'm "having a laugh". I'm very clearly talking about people I know personally - people who are my friends and my extended family. I think I know rather better than you how those people voted since we discussed it at the time. It would seem rather presumptuous of you to think you know their voting actions better than I do.
Perhaps what you meant to say was "Your experiences are different to mine". It's a shame you didn't.
