There are certain laws and laws have purposes. Circumcision, for example, is to check the male sex drive (kind of like women shame other women to prevent hypergamy). Circumcision is also a reminder to prevent race mixing.
Jesus flaunted all these laws. Just because he wanted him and his butt buddies to get tolerated.
I'm sure there were a lot of Samaritans and Greeks who were good people, but they were invasive foreigners who took over the country from the indigenous negroid Jews. Unlike the Greeks, The Samaritans had the same religion as the Jews. But they were racially alien.
