I've been wondering this for years. I see people who claim to have such high standards and want people of the same caliber to write with, but then they only write female main characters and sometimes only these select pre made female main characters. At what point does being unable or unwilling to tackle writing from a different perspective finally justify not being able to consider yourself an advanced writer?

This is not a call out post, I struggle with the exact opposite some times in only wanting to write male characters. But I can do both and strive to de decent at both. I get having a wheel house but come on. At some point refusing to write a whole segment of the gender population has to have an impact on your writing skills. 

Thoughts?
