Issues in BL

I'm just wondering how far you can go to justify a seme's actions in a bl. I used to eat up whatever yaoi authors would write, but now that I've taken a break from reading and am coming I'm seeing so much shit that authors just let pass because the top is hot and powerful.

While its more rare, another question is a bottom's justification. Have you ever read a bl where the bottom was clearly the problem, but it was swept under the rug because whatever.

Thoughts?
