I can discriminate you because it's you. I don't like you and I don't want to do business with you. End of story.
It's your problem to prove that it was racially or religiously motivated or something.
It's not a strong statement it's a fact.
You cannot force anybody to do business with you. Not me, can't force my brother, can't force my mother's laundry to have you as client.
Guess what? I can't force other companies to do business with me too! I can't force a lawyer to have me as a client, nor I can force a bank, nor an insurance.
Do you know how many countless "no"s companies I worked in got?
API companies unwilling to have us as clients because too small. Wanting to open the wallet? Not enough if we can't prove we can't ramp it up fast.
What could we do? Nothing.
Stripe or other payment processors can notoriously deny you services without owning you any explanation.
You just can't. Business is about trading and I can't be forced to trade with those I don't want to, nor they can be if they don't want me, for whatever reason (unless discrimination can be proven).
The only businesses that most laws force to offer a service are public utilities and even then, I can guarantee you 100%, that even banks if they don't want you as a client, even if they are among the few businesses that have, they still won't have you and rather drag this through courts and then maliciously comply to the point of effectively being unbanked.
