I went to a bilingual school district, Gadsden High Schools in Anthony, New Mexico, where, gasp, Mexican kids and Anglo kids all went to the same classes together. We all learned English together and we all learned Spanish together, for twelve years, and the best part is, we all were friends. Sad to say that could probably never happen again. I am so lucky I read and speak both languages fluently in this day and age. People miss out on so many things because they are scared.
Our country was founded on religious freedom. It is not illegal to make someone sit in the back of the bus. YOU may not like it, but they don't seem to mind. Those women are probably on the safest bus in New York, and if they want to sit in the back of the bus, let them, and if my mom and sister were riding that bus and had to sit in back and didn't get raped, mugged or robbed, then it's worth it. Those people aren't getting something special that you aren't getting and you never would have known about this bus anyhow, so just...shut up. Leave people alone!
If you 'must' ride that particular bus, then pay your money, sit down and shut up. Have some respect and just leave them alone. Go pick on a politician or someone who is really causing some problems.
