Why is it "des" here, when there is (presumably) only one Martine?

Would it be correct to use the three-layer structure I wrote down below, when building sentences with double pronouns? Imagine it like a matrix with three columns:

ME, TE, SE, NOUS, VOUS   |   LE, LA, LES   |   LUI, LEUR

Ex  Nous vous | les envoyons demain. | e_m_p_t_y

Ex  e_m_p_t_y | Je la | leur explique clairement.

Ex  Je vous | la donne. | e_m_p_t_y

Ex  e_m_p_t_y | Je la | lui donne.

I'm not sure why my answer was not accepted. Appreciate any insight. Thanks!

It seems to me in the phrase 

Je n'aime pas non plus certains supporters qui peuvent être violents ou même racistes

It should be either "violentes ou racistes" ou "violents ou racists".  If the reference is "supporteurs" , I would think it would be masculine, making the adjectives masculine.

Isn't "après-midi" masculine, and if so should it not be:

cet après-midi sera consacré

How do you know what gender a word is if it's not a person

Would someone please explain to me why you would write "Je me brosse les dents deux fois par jour." in stead of "Je me brosse mes dents ..." I'm uncertain why you couldn't use mes even though you're also using the reflexive verb. Merci!
