Thank you. Your devotion to the Universal Mother is admirable as well
No, I wouldn't love Her any less if She were absolutely hideous. I love Dhumavati Mahavidya as well, although in from a worldly point of view, She's not exactly attractive.
But, it is said that when Srimati Radhika takes form, there is a specific set of characteristics by which we can recgnize the Mother in Her form. While, on the other hand, when Dhumavati Mahavidya takes form, we can tell who is Her incarnation based on the characteristics we are given describing Her from Tantric Shastra. This doesn't mean that Dhumavati is less beautiful than Radharani, or that Radharani is more beautiful than Dhumavati. It just means that Devi lets us know how She's incarnating based on many things, including how Her form is.
So, that being said, I acknowledge Amma as being just as filled with divine light as Anandamayi Mata, for example. Although They both have rather different physical characteristics, They are both beacons of light in darkness, just as Radharani and Dhumavati are. But, we will know if it is Dhumavati or Radharani incarnating (if They choose to incarnate again) based on many things, among them physical characteristics. I'm sorry for having offended either you or Dhumavati Mahavidya. I offer all apologies to your feet and the lotus feet of the Divine Mahavidya Dhumavati.
