In the end, the arguments are pointless. I think it comes down to what makes each individual person comfortable. And for many women, they wear makeup not because they're trying to mask what they really look like, but rather because they feel it improves upon what they already have and it gives them a boost of confidence, which can be helpful both at work and on a date. Other women are comfortable just the way they are, without makeup. And some, for other reasons, wouldn't dare leave the house without it - not because they're trying to deceive people and put up a false front, but in the case of extreme facial discoloration or scarring people are rude and tend to stare and point, sometimes without realising it.
So, each person has to decide for themselves. It is nice to hear that a guy doesn't much care for makeup, because from the youngest age that most of us ladies can remember, we were taught that makeup makes you more "beautiful", and guys want girls who are beautiful. In media, advertising, and television/movies, the girl never attracts the attention of guys until AFTER a makeover. It's conditioning. And the need to feel beautiful and for others to find you beautiful is deeply ingrained, even without the media's influence. The media merely dictates what is considered beauty (including emaciated celebrities). It can be difficult to overcome that kind of conditioning.
If the makeup issue bothers the guys that much, then there are definitely girls out there who do not wear makeup, whom are available. But also, if you are already dating someone, or you have a girl in mind whom you would like to date, but the makeup thing gets to you, tell them that they are beautiful whether they wear makeup or not. I have no doubt that they would appreciate hearing it, even if it is not a guarantee that they'll stop. The reasons for wearing makeup are numerous and different, and each woman wears makeup for different reasons.
As for makeup smelling terrible, a) that smell really depends on the type of makeup - not all makeup smells, and b) if it really, really reeks, it's a sign that the makeup is old and has gone bad and needs to be thrown out. I don't like smelly makeup either.
Everyone has different views, and it is perfectly fine to express those views. You know, though...I've been thinking about all of this social conditioning... whoever told women they had to start shaving their legs and underarms to be "feminine" and beautiful? It really is a pain. Hmm. Maybe I'll just stop shaving....

Okay, kidding!
