Make up doesn't have to be paint like lol, and fake nails are for the rich (haha)... I wear makeup because 1. I don't like sunscreen on my face and so make up with an SPF in it is the best alternative and 2. Even skin-tone and no dark circles under my eyes (which is a genetic pigment issue, not a diet/sleep issue for me) gives me a boost in self-esteem when I am out in public.
I don't wear make up everyday, I don't wear it to go to the library or the shops (usually, unless its a really bad-skin day) but when I dress for the occasion (work, weddings, events, church etc) its going to look nicer... and I LIKE looking presentable, is that a crime? I'm not blessed with overly attractive features or body and so I have to work with what I am given.
I think while your comments are valid and allowed - they are very generalised and sterotypical.. not all women wearing make-up look like clowns. I bet you wouldn't even know some people had it on!!

so there....
