How are people in this century not understanding that humans produce animals for consumption and that eating animals' meat does not come from a magical apparition. We don't eat cows that are out there, we create cows for you to eat (under 4 years)
I don't think that's what's happening here and I don't know of anyone who does that. Words do offend people, that is not something you have to try hard to do.
I'm not a native English speaker and I don't see how this could be offending. Or maybe this is some US thing?
People have different skin colors, you can talk about it there is nothing special about it
You can disguise as someone without changing your skin color to match theirs. It's not part of the costume or character, skin is just part of their body as a human
Quick question, why do you think this site is for US people?
I don't think DH is accurately relating to this. DH key exchange is used to generate a shared secret to use symmetric cryptography by two entities from (generally temporary) private keys, which are not specifically associated with a public key (this is not a public/private key pair)
To me, two examples of public/private key usage are RSA (asymmetric cryptography) and for example SSH authentication with a key pair. DH key exchange can be used in SSH to encrypt communication, before authentication even begins
Indeed, great memory comrade
