To an extent. :-)
I disagree that Zach got a free pass from fans. I don't know what correspondence you may have gotten, but I know that I and many others were extremely upset that Zach was involved in Spawngate. Fans DID call out of character writing for BOTH Bianca and Zach.
I do agree that if you happen to like Zach more than Bianca, you're going to be willing to overlook his flaws more easily than her's, but the reverse is true as well. I've seen some fans completely excuse Bianca's actions and even say, "Kendall deserved it."
As for Reese, why would we say it's the writing for her? We don't know this character at all so we're only going by what we see and what AMC has presented to us is a weak, whiney, clingy, selfish character. That may not have been their intention, but it's how she comes across and remember, Reese so proudly declared to everyone many times it was SHE who convinced Zach to donate.
Another thing I have to disagree with you is the comment about holding the soaps responsible for the treatment of women just because we're willing to let a male character's actions slide. I don't believe that's true. I do think many, many, many viewers have been screaming long and loud for years about the treatment of women on soaps, but the shows and the networks simply don't listen and it's got nothing to do with letting a male character's actions slide. I know the audience has been screaming about Ryan's behavior, yet the show constantly let's him get away with everything. Ryan is never held accountable for ONE thing and when a character does step up and call him on his actions, something bad usually happens to that character or he/she is a villain to begin with (I'm thinking David Hayward as an example). This abusive, violent jerk is actually called a hero by the show AND the network! Now with upcoming spoilers, Ryan, to me, is going to be even more repugnant and AMC just sinks lower into a cesspole of abusing women.
To blame the audience for what is simply a lack of respect for women that's shown by the soaps' producers and writers and the networks is misplaced. The audience DOES complain and tries to make itself heard, but shows and networks, and yes, the magazines too sometimes, simply don't listen. But what can we expect when an executive producer like Julie Hanan Carruthers blames the AUDIENCE for "re-writing" things such as Reese's pursuit of Zach or when a head writer like Charles Pratt decimates every female character, if he even writes for them, and has quotes like,
