You don't know this mom but it hurts

I was watching tv with my mom today while holding kota. I decided to watch teen mom. I found out how judgemental my mother is. This is our conversation:
mom: Ugh! I cant believe you can watch this
me: why?
mom: these are just a bunch of stupid whores. getting pregnant as a teenager its unbelieveable
me: mom how could you say that?
mom: what?
me: you dont know them and look at me im your daughter and look at your granddaughter. does that mean you are calling me a stupid whore
mom: well thats different
me: no its not
(awkward silence. my mom gets up and walks out of the room not looking at me or Kota)
another time we were in the mall when i was pregnant and a girl with a baby was in front of us in line to buy something. the baby started to cry.
mom: i wish she wud just shut that thing up
me: mom!
mom: well its her fault for getting pregnant with it she should learn to keep it quiet
me: i can't believe you
mom: its the truth
me: *sigh* please stop
mom: whatever
(i started tearing up a little)
mom: stop crying
me: im sorry
(my mom rolls her eyes)
I love my mom (sort of) but her little comments like that really hurt me. If shes this willing to insult other people in public like that then what does she say bout me when im not around? Really mom... your words hurt more than one person. please think bout what you say before you say it...
