Cant teach an old dog new tricks. Options

[*Mercy*]

(Wow im on a topic rampage)

I'm supposed to be meeting my future mother in law soon and my fiance [Who is white] warned me that his mother may point out the fact that im "coloured" and may not support the engagement.And i told him that was bullshit for her to even atempt to sit there and call me that colured girl.But he basically sat there and said that i souldent let it bother me because shes old and used to those kind of ways.WTF the woman blogs like crazy and even makes her own layout templates but shes too old to learn some tolerance to my race because shes OLD?Are you f**king kidding me?He in turn told me i was overreacting to this and said that she dosnt have to learn any better because she was a nurse for some veterans hospital and that "you cant teach a old dog new tricks"

Oh really?But you can teach a old dog how to code a DIV layout eh?

Should we really be so forgiving to older people because its something they learned from when they were younger and we cant really help about the way they think and treat other races,religions or sexual orentation?
Should I be known as the colured girl that seduced her son rather then the girl who her son fell in love with?

Actually it might work better in debate..idk..
