It's nothing personal, it's just a pet peeve when anyone takes a few surface qualities and says "Oh, since these very different characters have a lot of fans, surely they'll like this one character that appears to have some of the same qualities."
If I sounded snappish, then I do apologize. 
Let's take an example. Morrigan, I loved her. Miranda, I loved her. Vivienne massively appealed to me. And they are all different. There's a good chance that a character that fits the archetype of the ice queen might pleases me. That doesn't mean that I will necessarily like her. But there's a potential. It's not an insult, if someone thinks that an Li, - generally those who know me - could interest me even if that might no be the case later.
Otherwise, I have never said in my life that x is exactly like y , because he is sharing one or two qualities lol. This is exactly what I don't like actually. Like people saying, Vivienne is Morrigan 2.0 because they have the same archetype.
And don't worry, It might be me who is seeing things, I'm not really in a good mood either. But my comment was neutral.
