Mosherose;
tzippi is absolutely correct.
We are supposed to be nice to people because that we are supposed to actually care about people.
If you care about people, of course you will be nice to non-jews also.
Seems to me that in your system, we are nice to Jews because it is a “mitzva”.
This is a perversion of the purpose of the Torah, which is intended to perfect us, not to create artificial standards.
Also, I don’t need your “mitzvos”. If you don’t care about me, I’d rather you just be nasty
