Let’s continue with the dialogue:
“Now, it seems to me, the procession of the native inhabitants was fine; but the one the Thracians conducted was no less fitting a show.”
Notice the distance implied in Socrates’s formulation: he refers to his fellow citizens as “native inhabitants” and goes on to praise the Thracians. The Athenians were civilized; the Thracians were barbarians. In fact, the Thracians had a game of chicken where they would hang themselves from the neck to see who could last the longest.
Socrates’s formulation and evaluation is an indication that he does not succumb to love of one’s own – he is able to praise and blame the domestic and the foreign alike. Socrates the philosopher is less tied to the city than the average person.
