Latinas with white boys

I've seen alot of posts lately with race issues. Im Latina and my man, my "Papi Chulo" is a White man. My father and my maternal grandmother hate against my husband because he's White and I crossed lines? My grandmother doesn't want or have anything to do with me or my children because they're mixed. My racist af MIL hates me and my children because her son mixed with Hispanic. Mind you she'll say she loves my children but when in a drunken rage will call us "Spiks" and "Niggers". It breaks my heart into a million pieces because my babies think the world of their Nanny. It disgusts me because they dnt knw the truth and for right now I'll shelter them from knowing exactly wht tht B!tch thinks of them, us but ik for a fact they'll know when they get older because she'll be f*ckin ignorant enough to say some shit. She keeps saying shit, commenting on their olive/light tan skin, their brown eyes, etc. Mind you I have light tan skin, brown eyes..My father and his fam came to the States in 75 from the Island. Of course they're gonna have some Hispanic features..How would you guys handle this? Im not just asking Latinas to answer this..Any female (: Thank You In Advance for ANY advice
