down syndrome awareness

I know a girl whose smile lights up the world, whose frown tugs at the heart strings, and whose tears can melt the hardest of hearts. This little girl has Down Syndrome.
When disability is a storyline, a rare feat in itself, it's often a tragic plot point or sensationalized heroism. Even more troublesome, the character is usually portrayed by an actor without a disability.
"[I]t’s not OK to leave someone out because of their disability, race, or gender."
"We can change the way some people perceive Down syndrome."
While it is important to celebrate all the things that people with Down syndrome can do and how similar they are to others, I would argue it is equally important to acknowledge the ongoing fight against discrimination that their differences evoke.
This has been my dilemma as Marcus and I have met each new group. Should we talk about Down syndrome? And to what extent? It is, after all, Down Syndrome Awareness Month, and Marcus does happen to have Down syndrome.
