She could've presented her critique without turning it into a gender issue:
>I won't be the nice girl anymore.
>I won't be the nice girl anymore.
Please note that when she points out Linus' behaviour, it is not because she got flamed. She did not get yelled at. The whole issue has nothing to do with her sex.
You are trying to turn it into a gender issue, which it is not - regardless of Sarah's stances on that matter.
While verbal abuse is not acceptable, neither is the male-shaming language she is using there.
I won't be the nice guy anymore.
