Those situations aren't comparable. While I oppose bigoted behavior by US citizens, for better or worse they have an absolute and inviolable right to remain in this country. Aliens generally have no such right. Entering and remaining in the country is a privilege. I oppose arbitrary arrests and deportations conducted without due process, but in principle there's nothing wrong with holding aliens to a different standard than citizens.

From a political standpoint, why should US citizens pay taxes to educate people who are apparently hostile to our fundamental values?

Because that's where Americans come from - the educated and acculturated sons and daughters of immigrants who came bearing all manner of prejudice.
