@Yaneph0 While there are certainly racists out there in the world, be they hosts, guests or none of the above, there are many reasons why a host might decline an inquiry or request having nothing to do with discrimination. (Of course, I don't know this host, so have no idea what his reason for declining was). The previous host gave you one possible explanation. When I looked at your profile (which I almost always do when responding here to guests or other hosts, so I'm not just talking through my hat) what jumped out at me is that while it says you have been a member since 2017, you don't have even one review. That can be a red flag to many hosts, although when I get requests from profiles like that, I ask the guest to please tell me why that would be. Usually it's quite innocent- they either joined planning to travel but never did, they'd had a few Airbnb stays, but the host hadn't bothered to leave a review, etc. Many hosts simply refuse to accept guests without a few good reviews- there have been far too many cases of guests, be they white, black, or brown, trashing homes, and they don't want to take that risk.
Initial communication from a guest also affects how a host responds. Your message to the host was rather accusing. A guest message that puts hosts at ease is informative, and friendly, rather than just asking them a question. Such as "Hi XX, my husband and I have been having a lovely holiday in France, so much so that we've decided to extend our trip. Your place looks lovely and we're quite interested. I'm wondering, though, about your security deposit. Could you please clarify that?"
Also, your question about the deposit is rather odd- of course a security deposit is over and above the cost of the accommodation, just as a security deposit on a home you would rent long term to live in is over and above the actual rent. It's a way of ensuring that the renters behave responsibly. Not all hosts have a security deposit, but hosts who've had some bad guest experiences, or those with high-end properties may have hefty ones. If you behave responsibly and leave the place clean and tidy, you'd have nothing to worry about in that regard.
So please don't just assume that because a host turns you down, that it's because they are racist. ( I'd never defend a racist, I abhor those attitudes) Hosts aren't obligated to give a reason for declining, just as guests aren't obligated to provide a reason for deciding to cancel a reservation they've made. Altho it's certainly nice and polite if they do so.
One thing I'd suggest, since you don't have any reviews yet, is that you fill out your profile information a bit. The one line that's there now doesn't say much about you, so it will help to make hosts feel more comfortable to accept a booking if they can read more about what you say about yourself and your interests.. And do try to be a bit more personable when you send a host an Inquiry or Booking Request- Airbnb hosts are just people listing their homes- we aren't impersonal hotels and we appreciate warm human communication
