Sorry for the 
link but this isn't really picked up anywhere else. Predictably, the same disgusting people (referring to H3, Destiny, etc) who spread the dubious "Hasan shocked his dog" stuff don't care about this one, so it isn't all over the internet.
I'm not posting this to own everyone who said they like Hasan, but I do think it's an important thing to point out to any fans of his on this site that animal rights have always been a huge weak point for him. I'm a casual watcher who was tuning in for the China adventures, but 
so after the Panda zoo and this, I'm out for good.
Horse racing is such an obviously gross and abusive sport to anyone with sight to see it, so it's annoying seeing how many people (though admittedly in collapsed comments) in his community just don't care at all. Beyond the comments there, but in his chat in real time any time animal rights or veganism are mentioned.
Tangentially related, but 
s here should recognize that gacha slop like Uma Musume also funds horse racing (the franchise is basically PR for the Japan Racing Association) and is only a small separation from betting at the track. It was obnoxious seeing the wave of people talking about it at launch and seeing it plastered all over gaming sites, Steam, etc. Most people probably don't think twice about it because horse girls in anime just 'makes sense' in a vacuum, but I want to bring more attention to the cruel industry by using that franchise and Hasan as a springboard.
Please educate your favorite streamer, celebrity, or whoever so they don't use their platforms to promote animal abuse.
Edit: lmao their mods locked the thread that was significantly more supportive of the idea that races are abuse.
If you really wanted to target this, an effective approach would be to start with jumps. Last year in British horse racing for example 80% of all horse deaths were in jump racing. 156 total deaths were jumps. You'd cut that down to 30-40 if you just banned jump racing.
That's an order of magnitude more horse deaths than I would have guessed. That's fucked.
Jump racing is really really bad for the horses. Multiple horses die every year at the Grand National which has the biggest jumps. Very few people will disagree except tory shitters. Keep in mind, this is from a total of somewhere around 88,000 horses that participate in racing (combining both jump and flat) if i recall correctly. Flat still kills though through overexertion or falls, just nowhere near the same level, it's really easy to convince people that jump racing is not good.
It all makes sense, I'm (.. surprised that I'm) surprised to learn how much worse it is than flat racing. I grew up next to a horse competition facility that had and still has quite large jump meets every weekend. Super unnecessary.
Australia can't even comprehensively ban dog racing. One state's ban on the export of greyhounds for racing only comes into effect next year. Shits bleak.
