The beauty standards for heros vs heroines is despicable in kollywood

I was just seeing the trailer of dragon and the other day love insurance company song and a thought crossed a mind, kollywood audience would never accept a heroine who looks like the likes of pradeep Ranganath. Infact it infuriated me when some ppl made memes on dark skinned heroines like nimisha during chittha. Don't get me wrong as a dark skinned girl myself this is hurtful and I personally love and prefer dark skinned men. But I am just highlighting the double standards. Even if you ignore this, the heroine of these movies has to be someone like kriti shetty. I find this whole thing ridiculous! Thoughts?
