I still do plan on contributing stuff back to Gentoo, but atleast as a user I can just ignore anyone that acts like an ass towards me. All of the developers that say, "Just ignore the devs that treat you like shit" are only hurting the project in the end. When everyone turns a blind eye to these people, they support their behaviour, and it will only continue to get worse. By ignoring them, you only hurt the project, and I hope those people that are doing the ignoring are coming to realize this.
