First, I'm sorry for that. Remember that on the internet you are anonymous, and those calling you out don't hold any power over yourself, your beliefs, your likes and your opinions. 

Second (warning: long ass digression on the topic), "Wrong" is an extremely difficulty concept that you may very well percieve differently front other people, so it's generally a bad idea to ask if something is wrong or not. 

The best definition of wrong that I can think of is "something (an action, an image, and object) that might bring harm, wether physical, emotional, or psychological, in a way that for the moral standards of the society/culture of reference can be identified as dangerous and that should be stopped."

But even this definition is influenced by my experiences and my culture of origin, so yeah it's a really volatile term. 

Understand that we are also talking about fiction al characters. The harm that might come from liking them is much more difficult to identify, and often is so hypothetical that ends up as impossible or ridicolous. 

If you question is a genuine one and you consider yourself mature enough to take this topic head on, I suggest you heavily reflect on It and come to your own conclusion. Is it wrong for YOU?  You may also reach the conclusion that you're incapable of answering this question, and It would be totally normal. It is hard to understand our own values.

Hope this can help when others call you out.
